When you were at a high point in your life, what was it about that time that was different?

Ask yourself, where am I now on the emotional scale? High? Great, grab a pen and paper, make note of what is going well and keep it.
Are you feeling low? Sit quietly and reflect on a time when you were at a high point. What was different about that time? How were your engaged, motivated or energized? Make a note and bring that to this moment.
Are you bored? Invite a beginners mind to your state.
