Great question and it's one that is driving my current plans for 2014 "to wake up and do what I want to do".
I would spend a lot more time with my wife and daughter even in the small things such as taking my girl to school and picking her up.
I would spend more time being aware, walking and meditating.
I would then spend a huge chunk of time giving somehow. I have a few projects me and my wife are starting in this area such as running a free course for new parents on how to resuscitate babies, top 5 risks for new borns etc
And travel!
