Weird problem: How to get confidence to give confidence advice?

I'm a 23 yo man.

Born in Mongolia, spent 3 years in Japan, went to study in the US, the quit to join the Mongolian army, and then came to China to do business. I did everything myself too, I'm not one of those rich kids that just travel around, I struggled through all of these haha.

Point is: I've been through quite a bit for a 23-year-old.

I feel like I understand how to be confident, overcoming anxiety and improving your self-esteem and stuff like that. Like I feel like I can solve that problem really well for people.

I see all these therapists and online coaches giving out advice that are mostly BS and I feel like I can do it wayyy better. You know how much money these people make? haha

The problem I always felt like "Who the hell am I to teach confidence to people?"

Like when I'm just sitting alone, I feel like I'm not that above. But when I go out and mingle with people, I realize just how low people's self-esteems are, how unconfident people are. How scared people are in general. It's not just socially either, people are so scared of making any moves in their lives.

And it's like I can fix that.

Idk maybe I think coaching is BS or I'm actually not confident enough to charge for it haha.

What do I do here? Nothing too serious, just flying a thought I always had. Not end all, be all.
