Let Go of the Past and Live in the Present Moment
If your past experiences don't encourage you to move forward, then apparently, you must let go of such memories. Dwelling on such can insinuate and instill failure!
You may have hurt someone in the past or vice versa. You may have had ugly experiences in the past; you may have encountered a misfortune or miserable outcome in the past; you may have received denial, depravity, or destitution in the past. Whichever it is, the future is always better and brighter than the past, if only you can develop a positive orientation of the mindset.
