For me, the more I don't foolishly waste my life wishing for a better past the more free I am today to create, grow, and love.
Most likely, when you are upset for any reason, it is rare that you will want to quickly see the real cause of your upset or the solution, but with practice you can begin to ask yourself honestly, is it the person/situation or is it my unforgiving thoughts about this person and the past that are upsetting me?
Becoming less focused on the past and future and not resisting the moment is how to overcome fear, physical pain, and all suffering.
