My job is all about moving. People don't need me if they aren't making changes in their lives. So I really love this advice:
The past has a purpose in our life. But too many people retreat to the past and take up residency. Yesterday is about learning lessons. It's okay to revisit the past and find a lesson to improve today. But its not okay to relive it. Reliving steals the meaning from today because it doesn't allow you to see today's opportunities that are right in front of you. Live in Today.
