Look at the past fondly, forget the mistakes because we can do nothing to change them. Heed these words from the song My Way by the Chairman of the Board,

Regrets, I've had a few,
but then again, too few to mention.
I did what I had to do
and saw it through without exception

I planned each charted course,
Each careful step along the byway,
But more, much more than this,
I did it my way.

Know in your heart that "your way" is the only option you have open to you. You did it the way you felt was right at the time, raise your head and smile.

Look ahead with hope and anticipation of good to come in the future knowing so many care about you.
