I love who I am and know I can be better.

These are usually treated as opposing forces — as though accepting yourself must involve giving up on improvement, and wanting to improve must involve a low opinion.

Anyone who has been well taught knows otherwise. The best teacher you ever had clearly thought you were worth something and clearly expected more. Neither cancelled the other. The expectation was legible as a form of regard.

You are allowed to hold both positions about yourself at once. Most people who go on improving for decades are running exactly that arrangement.
