"Success will never be a big step in the future, success is a small step taken just now." Jonatan Mårtensson

Looking back, it is so much easier to see the things we could have done differently or the things we should have done. "If only," or "I should have...." or "Why didn't I just...?" 

The first lesson we need to learn is to quit looking back. Don't let your past hold you back. Believe in yourself and know that you are right where you are supposed to be. It's your choice how you go forward. 

Don't doubt and never look back.
