Somebody told you a falsehood if they told you that you have to live with your past decisions, choices, and actions.
The past is past and has nothing to do with you.
It has nothing to do with Right Now.
Do not let anything from your past inhibit you in this Present Moment. Start over. Start Fresh. Each day.
Each hour, if it serves you. Heck, each minute. Just get going. Just do it.
Just say it. With love.
All else will take care of itself.
