“The moment you doubt whether you can fly, you cease for ever to be able to do it.”
– J.M. Barrie
I feel like we tend to assume that to continue growing at a skill we have to assume that we are bad at it.
That simply is not the truth though, you can be confident in something, and believe you are good at it and continue to improve your craft.
It does not make you cocky or naive, it does not mean you are off in la-la land, it means you know your worth. You understand that you have worked hard to get to where you are and expect people to see that.
No one is perfect, it is something you can strive for but never achieve. Therefore our expectations for yourself should be to be perfect but to improve. To know where you started, how far you have come, and where you are headed.
Be confident, good, and improving. What more could you want in life?
