I have had to forgive myself for a few big things, millions of little things, and still haven't made it around to forgiving myself for some not-quite-so-big things.

I think there isn't any one right way to do it. I would have to say that it is important to try to learn from the mistake, and grow as a person from it.

I think it's also import to set any wrongs right, if that is within your power. Make up for whatever it is.

I also believe that it is important to be kind to one's self. Think of how you would feel if anything person did to you the wrong about which you're feeling guilty? Sometimes it's more difficult to forgive ourselves than it is to forgive others.

P.S. seeing Penfold made me smile.
