It is never too late.
This is a reminder that you can always start over. What you did yesterday, last week, last month, last year, does not define you. Every moment is a new chance to be a better version of yourself. So whatever wrong you felt you did or mistakes you have made that your mind is constantly replaying causing you to suffer, does not define the rest of your life. It is never too late to make new choices, to change your perspective, to try harder, to take a risk, to be happy. Stop focusing on what was taken away. Be grateful that you have the opportunity to learn and apply that wisdom to each new encounter in your life.
