Commit yourself to becoming that person. Use whatever life gives you this moment to become the person of whom you have dreamed. Exercise the human freedom to choose your response to the people and conditions around you. I tell you now, never again settle for less than what you can become. Do not worry about making a mistake or choosing the wrong path.
Life is either a daring adventure or nothing at all.
What you leave behind is not as important as how you've lived. Know that you will learn from your mistakes and every wrong attempt is simply another step forward on the journey. It is the journey that is the reward. No superhuman act will have the power to turn your problems around. Life is cumulative.
