If you have to let go of everything else to get a good hold on this, do it.
Care. Madly, passionately.
Be yourself. There's no such thing as "larger than life"; be fully alive and present and true and it doesn't get more important than that.
Laugh. Loud, long, often.
Smile. And get other people to do it too.
Be kind. Randomly, bewilderingly, unexpectedly, sweetly.
