It really puts things into perspective and I have brought this up in Wabeno one time and someone found it useful right away.
I’ve had someone upset 10 seconds of my time over twenty years ago and it still crops up and bug me! I’m sure that person has long since forgotten what they did and moved on. That is why I am constantly on the path of bettering myself and learning. Hay House has many books to help people on their own paths.
The next time someone or something upsets you try to think of this quote and think if this would matter 15 minutes from now, a day from now, or even 20 years from now.
