Ask For Feedback from a Professional
You might have spent months or years honing your skills in a particular area, but you're still worried that you're not good enough.
Find someone professional, and ask them for their opinions. If you're hoping to write a best-selling novel, hire a writing coach or editor. If you're planning to start up a restaurant, ask for advice from someone who's done the same thing. You'll find out that you're doing a lot of things right (and you'll also get a few tips on how to make improvements).
Consider hiring a coach, or joining a small group or class. You could look locally or online.
