It's better to look ahead and prepare, than to look back and regret. Jackie Joyner-Kersee

1. Focus on others' regrets- think about what others may have to regret.
2. Let others motivate you- It takes a team
3. Shift from inner to outer focus- It's not all about you
4. Write out your angst-write it out
5. Practice positive thinking- It starts in the mind
6. Assess your actions-adapt,overcome,achieve
7. Set new goals-never too late to change
8. Seek help-Different perspectives help
