Sure there are some things that are beyond our control, but so much of life, what we can achieve, where we are, our problems, our issues, our ability to improve ourselves and the world around us, comes down to personal choice and personal decisions.
To stay miserable, to remain struggling, etc. because that’s the “easy” way is tragic. Making changes for improvement may be hard work, but I’ve never heard of anyone who regretted doing it.
I have made plenty of mistakes and more than enough stupid decisions, but I am willing to take complete personal responsibility for those mistakes and try to learn and grow from the experience. No one is perfect and I’ve made the same dumb mistakes a couple of times before learning….but the important part IS to learn something from it, own it and not blame others or circumstances for who we are and where we are in life. If you own it, you can change it and that’s personal power!
