I do. It's. Work in progress. I think if I didn't have crippling mental health issues I'd be able to learn and live a better life in the future. Which I think is the best way to think about it.
If it's career related - they say the best time to plant a tree is 20 years ago. The second best time is now.
If it's morality related - just remember Jesus said 'let the person who is without sin here cast the first stone' and we all know what happened after that.
We're all sinners. We all sin. All we can do is learn from it and live a better life. You can do it!
