The way that I get past that is thinking that in the past I was making decisions based on the information that I had at the time. For example, I used to ruminate about the past a lot, second-guessing everything that I did and wishing I had done something differently. This kind of thinking really upset me and kept me in the past instead of propelling me forward.
Now that I have moved beyond my ruminating ways, I wake up more clear-headed, I am more present in my every-day life and I am in general happier. Sometimes I wonder... why didn't I figure this out 10 years ago - imagine the hours, days, months or even (god help me!) years I could have used being more productive and more present!
But... that way of thinking will... again keep me in the past and not allow me to move forward. I want to move forward so badly, that it gives me the strength to ignore those thoughts.
To counteract further worries, I think "I was just doing my best at the time, with the information that I had." Life is a journey, so everyone is at their own stage of development. Good luck!
