1. You have to actually do stuff:
Most actors don't make money or get acting work because they sit back and expect their agent to get them all their work. They work in coffee shops and go "my agents got me nothing this month". They don't...
-Apply for jobs
-Make their own plays/films/whatever
-Ring their agent to suggest things.
-Learn new skills to project themselves (writing, directing, editing, filming, comparing, choreographing)
- etc etc etc
You'll be a lot luckier if you do more things.
2.Persistence (keep doing stuff):
It takes a while for people to notice but eventually they do. If you write a play a year and put it on for seven years, you'll be a better playwright and actor, and maybe one of those seven scripts will be half decent. Jus keep doing it.
You'll be a lot luckier still if you do more things for longer.
3. Make choices/ take risks.
I don't really believe in talent, people just make better choices and take more risks. That's all talent is; the conclusion of a string of brave choices.
That's my advice :)
