Your goals are admirable, and I think you're on the right path. Do you have some product or company idea in mind already?
The one piece of advice I'd like to give you is, there's no need to rush. There will be plenty more YC intakes, and you'll have tons of good ideas - learning to execute on them by trying a bunch of different stuff is the best way to get there, and to do that you need to give yourself time to learn.
Thank for your feedback. I have two ideas in mind. One is about a process I would like to streamline using technology at my current job, and the other one deals with ESL and learning a new language. Many of the ESL or learn a language methods out there are so boring, and I think I have a way to make it less boring and actually learn something. I had this problem when I wanted to learn French. You can sit there and repeat all the French words until the cows come home, but it will be no use to you when you want to converse in real life situations. The idea is about learning a new language in a way that is engaging, not learning from a CD and tucked away in your bedroom.
