Our past actions may sometimes haunt us, but they do not necessarily define us.
A very successful person is someone who has tried and failed many times. If you aren't successful yet, then maybe you haven't failed enough. Be brave and be willing to make mistakes. Failure is feedback; it is not a reason to give up.
Failure can feel like emotional baggage that we must carry around with us forever. You don't have to. Ditch that weight and free yourself.
