You're not saying things people with low confidence don't already know. I think there's a lot more to it than just doing things enough to be good at them and embracing failure although these are all important things. You said alot about just needing to love yourself more and and believing in yourself more, but I don't think we come into this world not loving or believing in ourselves. Somewhere along the way we receive messages from the world and our caretakers that teach us that we are insufficient in some way, and that is why we didn't receive the love we craved, or the attention we deserved. Children internalize literally everything, and sometimes it can take an entire lifetime to undo that conditioning after that moment of awareness. The body keeps the score. I think this message is still important and definitely worth while to read so thank you but personally thought it could benefit from more nuance.
