How to make freelance better?

Have you ever thought about what you like about freelance and what you don't?
Are there any things that piss you off?
And those from whom you are delighted?

I am furious:
- customers who do not respect my work;
- Performers with thousands of excuses who suddenly disappear at the right time.

I like:
- that I can sleep as much as I want;
- that I can travel without breaking away from work.

What do you think can really be improved?
