If you think you must dwell on the past, conjure up your trials and tribulations, you give way to a severe drain on your power, and that will hold you captive to emotionality instead of reality. If you must go to your past, only go to those points where you were empowered, healthy, and whole. Eventually, you will build up enough power to stay ever-present because your reality does not happen behind you nor in front of you.
The real transformation in life is YOU, powerful, NOW! Be present, be strong, be life!
