1) Exercise, a lot. Put it first, so that you'll actually do it.
2) Eat right. These things, exercise and food, can have a far greater impact on your work than you might realize.
3) Discipline. Show up and put the time in. Force yourself.
4) Pomodoro technique. Commit to yourself that you'll put in 2 solid 45 minute periods per day. Work your way up from there. You need to do it even when you don't feel like it.
5) Get friends who encourage you to be your best. If you don't have friends like that, contact me unoti2@gmail.com
I would add:
- one more: do it fist time in the morning, i know it is hard, but after 30mins of coding you will feel good about your self end progress.
This way you and others can use the project as it develops. It's a lot more fun when you can play with a working prototype of your project at any given time, and you have users enjoying the service and requesting features. It's great motivation. Also, if you notice at step 3 or 4 that no one cares about your project, you can toss it in the garbage, move onto the next idea, and be glad you didn't wait until step 10 to launch and waste all that time.
When you bite off too much, the finish line is so far in the distance that you lose all motivation.
Also if the project isn't that complicated how good of a demo can it be to get you this undefined full time job? Honestly finishing school may help you more in the long run (unless what you're doing at school has nothing to do with your career).
