What do you splurge on that is completely unnecessary, but totally worth it?

Weekly massage? Track days for your sport car addiction? I've recently been told I'm too miserly with my money and hesitantly agree... So what do you spend freely on? I don't have yacht money, but a used ski boat is in the cards..

EDIT: So many great answers so keep them coming! I love seeing extremes from simply splurging on manicures all the way to Private jets!
