Help me control myself?

Put a thing on your PC so you can only use it for a couple of hours a day, like anti-child lock thing.
It's fine if you know how to get around it or have the password to unlock it. The trick is to add that extra barrier.
A barrier that doesn't have to be high but does need to be able to completely stop you.

It will help.

>How do I make myself set aside 2-3 hours each day for the things I dream of when I have so little drive?
Come up with goals that you really care about. You should be open to the possibility that you don't actually care that much about the dreams you thought you had. So sit down and really think about and write down what you want to do with your life and WHY. You need to reason through why these goals matter so much to you because when you're tempted to just say "fuck it" and vegetate in front of your computer, you'd better be able to convince yourself that moving toward your goals is more important. I think this lack of motivation is often due to not being clear to yourself about what your goals actually are and not having a plan.
So after you've given yourself goals and a clear, concrete plan to work toward them, schedule your time. Be sure to schedule time to play games or whatever if you think you'll miss doing that. You don't have to give up any of these things that have been a part of your life, but you need to give yourself time for the other things you believe are important. Following the schedule will require discipline, which is the hard part. But if you gave yourself goals that you actually give a shit about, then you'll have an easier time.
