Now I hate when people use phrases like "learning your own value" because while it sounds really nice, nobody explains how to actually do it .

Time to roll up your sleeves, bubba. We're gonna fix that.

Let's get to it...

It's " perceived ability to succeed at a given task ." It's a belief, not an objective measure of ability. But it's a thermonuclear powered belief and has an eye-popping effect on your life, whether you know what it is or not.

Perceived self-efficacy refers to beliefs in one's capabilities to organize and execute the courses of action required to produce given attainments... People's beliefs in their efficacy affect almost everything they do: how they think, motivate themselves, feel, and behave.

It can even be more important than skill. No doubt, actual skills are critical. If you have self-efficacy but no real driving ability, I'm not getting in your Uber. But that said, if you don't believe you can accomplish something, you probably won't try. And even if you do try, when you meet resistance, you'll give up.
