Bridging thoughts

I constantly in different areas of my life think this thought I’m not good enough, I need to be better or do better. I don’t believe the thought I’m worthy so I was wondering if you could help me and I wanted to ask your advice about the I need to be better or do better, these could be good thoughts but I use it as a way to be self critical, how could I shift it so it drives me to keep taking action and evolve into a better version of myself instead
