Your “past” has “passed” for a reason….
Don’t look back into you past expecting to move forward. You have passed it by for a reason. If whatever you are reaching back for is not in your present future, it is because that thing was not meant to be there. That thing could not nurture and support the place you are in right now. Perhaps it is a job, an old relationship, or a feeling. If you’re missing it, great! However, don’t let that period of mourning prevent you from continuing to march forward. Success in your destiny will not be marked by looking behind you and desiring to have the past catch up with you.
Keep this in mind; you can not get to the top of a mountain quickly by carrying unnecessary baggage along the way. The higher you climb may necessitate leaving some gear behind.
