There is so much more to FIRST tan building a robot. You are learning how to work with a diverse group of people. You are learning to interact with adults and probably spend more time talking with your teachers that are advisors than anyone else in your school. You are learning to be responsible for yourself when you travel with your team to new cities. You must constantly market and sell your team to maintain sponsors, to win awards at events and to recruit new members. You are becoming the leaders of tomorrow by leading today.
No matter where you end up - college, tech school, apprentice, straight to a job - your are going to be a better person from FIRST. And then, you can help inspire someone else by sponsoring a team or being a mentor or leader.
My guess is you will all be great at whatever you do.
