But we must also contend with the fact that most people -- ourselves included -- won't fix most of their flaws. Besides, your anecdote does not even further your point. You're talking about having the intention to try to improve yourself. That says nothing about whether you'll actually follow through, let alone succeed.
But who says they are flaws? I only believe in fixing self-accepted flaws.
Eg if someone can’t handle alcohol -> don’t drink
Fat? Eat less and exercise
ADHD? Get medicated and embrace the condition and understand it
I think you can pick and choose to work on your flaws. I certainly am after a life event, but sometimes it requires an external strong force to make you realise you want to change for the better
I feel this way of viewing the world is assuming that there is no room for personal growth -- a fixed mindset so to speak. And there's no guarantee that any of us can change anything, we can only try our best.
