Study the situation thoroughly, go over in your imagination the various courses of action possible to you and the consequences which can and may follow from each course. Pick out the course which gives the most promise—and go ahead. If we wait until we are absolutely certain and sure before we act we will never do anything. Any time you act you can be wrong. Any decision you make can turn out to be the wrong one. But we must not let this deter us from going after the goal we want. You must daily have the courage to risk making mistakes, risk failure, risk being humiliated. A step in the wrong direction is better than staying "on the spot" all your life. Once you're moving forward you can correct your course as you go. Your automatic guidance system cannot guide you when you're stalled, "standing still." —DR. MAXWELL MALTZ
This is something I can totally relate to. Many times in my life I took action, and there had been moments I got them right and many times wrong. In the beginning I felt guilty and terrible and miserable, but as I grow older I realize these actually add to my Experience Bank. Although it was only in my late twenties I began to see the point, I was a risk-taker right from the start when I was young.
Once in a while the feeling of regret for the mistakes I made still creeps in, BUT I'm nipping it in the bud!
