If you don't solve a problem, you can't expect for people to pay you, right?
If you just show up at your office but you don't do anything helpful, will your boss pay you money?
So if you don't know what you're good at, get new skills.
Find out what kind of problems people are having that you can help them with.
Solve those people's problems.
Sometimes do it for free or for testimonials.
Sometimes ask for money in return.
Then you'll make a living and people will start banging your door for help.
