However, that does not necessarily mean that you completely stop working on your startup. While being committed is important, there is a right time for everything and it may not be the best time to drop out of school... suppose an year down the line, you change your mind- it will be a lot harder and for you to get into good universities. The risks vs. benefits at this stage may be out of whack.
The important thing is that the idea should not die and should always be on the backburner until the time is right and you have the matured view of the world [and how cruel it can be] to make the whole scheme of things to work in your favor.
Just my 2 cents...
