Here are some simple guidelines more programmers in adult should follow. It will prevent drama, might save your reputation and will save money and time for everyone.

1 - Don't try to take programming jobs if you have absolutely no experience finishing full jobs on a deadline. You will fail any job you get if you have no experience with this - it's harder than it seems.
If you've never done any commercial work so far, train yourself by doing some simple open source jobs. Set yourself a deadline, and work towards it. When you've mastered that, try and make a simple commercial piece of software.
Whatever you do, don't take jobs that far exceed things you've done previously. You will fail or flake out - I guarantee it.

2 - Don't inflate your experience. If you do, you'll raise expectations you simply won't be able to meet.

3 - Give realistic timelines. No matter what the client wants, make sure there's enough time for mistakes, slip-ups, testing and rewrites. Otherwise, chances are you'll deliver buggy or insecure software. If the client is in a rush, make it clear how much time everything will cost.

4 - Don't take too many jobs at a time. It's a good policy to only take one at a time. If someone else wants to hire you in the mean time, let them know that you are currently working on a project, and that you will have to finish that first.

5 - Finish every single job you ever get. Flaking out on clients costs them money, and hurts your reputation.
