I’d like to add:
Judging other people in the gym without knowing their full story is unproductive. Focus on your shit.
There is nothing wrong with getting strong.
Sometimes ego is a good thing. I can’t tell you how often my ego pushed me to do more and better. I play the ego game. Sometimes I secretly compete with others at the gym - keeps me motivated.
Put your fucking weight back.
The gym is a positive place. Encourage others.
Ask questions, talk to others at the gym, and find out why they are doing what they are doing. There is always more to learn.
