I was listening to a Tom Petty song, "Crawling Back To You," and it had the line, "Most things I worry about happen any way."
And, "Every bad dream that comes my way turns to smoke upon closer inspection."
Of course this isn't an original thought, but we still struggle with it anyway.
My dad, in his mid 80s, said he would have enjoyed life more if he didn't worry about things that really didn't matter. Easier said than done, of course.
So, what have you worried about prior to travelling that was a waste of time and energy?
