Don't dig up the grave looking for life.
All you can find is bones. No matter how hard you dig/search for life and energy, you won’t find it in the “past”.
There might be pieces or fabrics of yourself in the past. Your actions, words and thoughts, some of which failed or were successful. It just doesn’t matter. It’s all over. The time won’t go back.
Instead look into the future. There is optimism and hope for betterment there.
You could have been a failure until today, but may be, just may be, you will have a better day tomorrow. Who knows.
Why should you delve in the past when you can paint a beautiful future in your mind?
Life is all about what you do going forward with what you have now. Not rewinding back to those old days, practices or processes.
