Perhaps it is, but I believe it's important to fight off any feelings of pride or narcissism.
The only variable I can change is myself, and thus I recognise that every single mistake or failure is mine and mine only. I believe that's the healthiest outlook on life that one can have.
Also, I think too I don't have any right to say what I'm worth - my worth is determined by how much my labor creates value for others. If I'm paid peanuts, that speaks badly of me.
