What's the single thing you'd undo in your life?

Hi myLotters! I sometimes look back and think about my mistakes in my life. If I would be given a chance to rectify my mistakes, I'd grab it for many that I've committed. But if I'd be given a single chance to correct only one mistake, I'd undo picking up the smoking habit!


What would you do? - one chance/one undo
