The best time to plant a tree was 20 years ago, the second best time is today.
Point being that is never too late to start.
Anything worth doing, is worth doing poorly.
Maybe you don't the motivation to give 100% today. Maybe you are not good enough to do it the right way. Doesn't matter. Don't just give up and do nothing. For example I may say I don't feel like going to the gym today and lifting weights. So instead of staying home and watching YouTube. I'll go walk on the treadmill for 20 minutes. Yeah it might not be as rigorous, and I might not have met my goal, but I did something.
