It's better to look ahead and prepare, than to look back and regret. Jackie Joyner-Kersee
Focus on others' regrets- think about what others may have to regret.
Let others motivate you- It takes a team
Shift from inner to outer focus- It's not all about you
Write out your angst-write it out
Practice positive thinking- It starts in the mind
Assess your actions-adapt,overcome,achieve
Set new goals-never too late to change
Seek help-Different perspectives help
