1 TRUST Yourself now
You know what you're doing. You really do. You think you don't but you do. You've doubted it because there wasn't a job for what you wanted to do. But you will create it. Lets be honest, you'll create that job even if you are hired to do something else. You sell stuff? You're being yourself while you do that... don't fool yourself. Go with it. Even if it takes you 70 years, you will do it. So start now, however you can.
