Keep showing up.
Making just $50 a day to me used to be insane hard. I now sometimes have 200k+ days.
Doing 1 BJJ session left me sore for days. Now I train 6 days a week 1-2 hours. Feel fine.
You will adapt. What is hard will become easy. You must suck first n you must keep showing up.
This is the price. It’s that simple. No one will stop you but you.
