If it’s in the past, it’s best to learn from it and leave it there, or you’ll never grow.
If you are dissatisfied and unhappy with the current direction in your life, then shut up and change it. Instead of wasting time making up a bunch of resolutions which you’ll more than likely not keep anyway, just get it done. Do what needs to be done, and waste no time doing it.
It’s a new year, with new beginnings.
