Self-esteem and self-confidence

Self-esteem and self-confidence, how to go past the barriers?

The same comment over and over again. No matter what is the topic or how long you've been involved with it, the feddback is always the same: “You have the skills, we know we can do it, if only you could believe it... You can do great. You just need to work on your self-confidence”.

How do you even build self-esteem? I mean I understand how you can promote other people's self-esteem, but does one develops its own?

The first step is identifying the problem. That's been done, and there's no doubt about it, but what does one do with that information then?

It's funny how people's opinion about someone's capabilities and skills can differ so much from the perception that that person has about herself.

It's a small curse because no matter how talented someone is, no matter how much they invest in something they'll always be holding themselves back because they simply don't believe it.

And rationally maybe they even know it doesn't make sense, but how do you change something that is such a big part of who you are? Where do you even start?
