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.

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.
