Working on you, having new experiences, setting new goals, learning about how to let go of past hurt (learn from the past, but don't re-live the painful emotions; rather, think of what they taught you and be grateful that you learned).
We can basically re-write our own past. Some folks have trouble with this, and they hold on to every regret, every hurt, every disappointment and re-live those emotions over and over and over. It's not a good way to go through life.
I cannot complain for not receiving from others, that which I've never asked them for.
