I was (am) having the same problem, so recently I've decided to join other people to see if that helps me commit to an idea (wasn't even my own). And it does!

IMHO I think you should struggle some more with your discipline problem, and then join an institution such as a start-up, HackerSchool, etc. Internships and programs are great because of the experience you'll get, knowledge and so on, but your lack of discipline when nobody's watching you will still probably be there afterwards. But that's just my opinion!
