My dreams, my goals, my Achievements..

How do you want to see yourself after 10 Yrs from now?
How do you want to see yourself after 5 Yrs from now?
How do you want to see yourself after 3 Yrs from now?
How do you want to see yourself after 1 Yr from now?

Have you done any planning for your future ? Yes NO ?

If the answer of the last question is NO then you should not regret 10 Yrs down the line what you will be achieving .. as you have left your future purely on your destiny.. so if you are a lucky person you will be something good.. BUT if not lucky enough then ...??

You have two choices :
1. Go and visit some priest or Baba and ask him how you can be lucky ?
2. Simply write on a blank paper what you want to become after 10 Yrs.

If your choice was "1" then again you left your destiny in the hand of your Priest or Baba..

If you choose "2" then you are the only person responsible for what you have written on that blank paper and responsibility lies on you to achieve it or not to achieve it..

I attended one 3 days seminar in March 2006, The trainer was a lady in her 40's. She told our batch we must have SMART (Specific, Measurable, Achievhable,Realistic, Time Bound) goals. And these goals should be Long term Goals and Short Term Goals. The long term Goals are set for 10 Yrs 5 Yrs, and 3 Yrs duration while the short term Goals are for 1 Yr, Monthly, Weekly and finally Dailly. She told us to set BIG goals and start taking small steps towards those BIG goals.I choose to quit Freescale after attending that seminar and today I am proud of my choice.

We must divide our bigger goals into smaller ones and their should be atleast 2 inch progress every week, Every Month and every Year.

If you follow this simple practice than you will be better than anything else and everything whatever you will be achieving will be planned by you and you will be the owner of each and every success which you will get.. and beleive me this will give you so much confidance and satisfaction which you will not be getting if you achieve the same or more by luck..

SO SET GOALS AND ACHIEVE IT, AND THIS WAY YOU WILL BECOME WHAT YOU WANT TO BE.. NOT SOMETHING ELSE..

So set your goals for the next week and start taking small steps on a dailly basis to achieve it...

Guys, What is your plan for next week? Weekend is over and now it is time to plan for the coming week.

Please feel free to post your comments directly on this blog..

How to choose your final year project? How important it is ?

The final year project is the main weapon for any engineer passing out from college. In almost all interviews there will be few questions on your final year project. And the interviewer expects you to deliver the best answer of all these project based questions as you are expected to go through the technology behind that project.
On many occasions if you are appearing in a small of medium sized company's interview than your selection is more based on your final year project as the smaller companies expects the productivity from day-1 and if you know the technology which falls under the product range of the hiring company than your selection chances becomes very high.

How to choose Final year Project?

This is the biggest question and the most important decision for the under graduates. As the most of the UG students does not have a fair idea about the impact of the final year project. They realise the importance much later and at that point of time they do not have time to correct it. Some students change their final year project while applying for the jobs but they lack the knowledge so they fails to explain the basic logic and rejected in the interviews.

Here are some tips to choose final year project:
* Choose HOT technology, which opens many job avenues.
* The domain should be wide and of your interest as it may be the domain for your life.
* Do not try to opt for very complex project
* Find some basic but innovative solution
* Try to make things simple
* Identify the tools and technology required to implement it.
* Discuss with some immediate seniors who are working in the Industry
* Check your labs and identify some Industry mentors apart from Teachers
* REMEMBER EXPECTATION FROM YOU IS TO KNOW THE PROCESS OF MAKING

I must emphasize here the importance of the Industry mentors, the presence of a Industry mentors can really change the direction of your career. As they are the people who are living the technology on a daily basis. They are the people who are involved in hiring so they know what they are looking for in a fresh candidate who will be joining them next year. It will also help you in networking inside the Industry. ( I will write in more detail about networking later as this is another important aspect)


Please forward this link to as many students as possible. I request all readers to start following this blog, As there will be a lot of stuff coming in on this page.

Please visit http://www.incise.in/ for finding a Industry mentor FREE OF COST. Or write me at incise.edu@gmail.com

Importance of B.Tech Projects

This blog is dedicated to the thousands of the students who are studying in BE, B. Tech, MCA, MSc, BSc streams and have been assigned to develop their final Year project as part of their degree completion requirement.

WHY I AM WRITING THIS BLOG?
Silicon Guru was sitting in his office inside BIG MNC and his HR manager walks in and give him a CV of a fresh engineer. He looks at the CV and was impressed with the details written in the CV of the fresh engineer and he was excited to meet the the engineer who is exactly matching with requirement, which Silicon Guru was looking for since long time. He is directly headed towards the meeting room where the fresh engineer was waiting for the interviewer.

Silicon Guru was greeted by him with a big smile and Good morning Sir...
Good Morning Rahul was the answer.. and then started the introduction round from both sides.. So far it was going good and Silicon Guru came to the point directly without wasting much time. And here come the first technical question from Silicon Guru.

"Rahul I am really impressed to see the project which you have developed in final year. Can you please explain what issues you encountered while you were developing this final year project?"
Silicon Guru was very much dis-appointed to hear the answer.. in fact there was no answer and after some talk Rahul admitted that he purchased his project from Sardarji's shop in Delhi by paying Rs 25K. This was not the first time Silicon Guru heard this confession from a engineer,Who was repenting on his decision to buy that project, This incident was happenning with him again and again.  And this prompted Silicon Guru to write this blog to make student's aware about the importance of final Year project.
Silicon Guru will throw more light on why Rahul and other Student's like Rahul purchase their projects later in this article.

ADVICE #1 NEVER EVER PURCHASE YOUR FINAL YEAR PROJECT
* As your final year project is your Biggest weapon while facing interview
* It is most likely that your CV is shortlisted just because of your Final Year Project
* You must know making of your Project, As the interviewer will be more interested in the issues which you faced while developing your project.

Some open Questions?
Does Rahul and his friends had enough technical support to develop the Final Year B. Tech project?
What facilities the college was providing to develop final year B.Tech Projects?
Was he forced to buy his final year project?

Choices ? Rahul choose to buy his project and because of that he lost one hard earned job opportunity. I have read it somewhere that:- "95% of our life is because of our choices and 5% is dependent on luck"
