One thing to always remember in life is that you can never go back to change the past, but you can change your future with actions from now. Forget the mistakes of yesterday you cannot change. As long as you live, as long as you’re alive, there is hope for success. Yesterday, last year, ten years ago, 20 years ago is the past. Even the last ten seconds is the past.
All you can do is learn from your mistakes from the past. It’ll help improve your future which can be 20 minutes from now, tomorrow,the next month, next year, 6 years later or 50 years. Or you can just keep waiting foolishly for a time machine. Or Just move on. Your choice.
