Drink less
Work harder/smarter
Study harder
Be less judgmental of the superficial bullshit of people around me, especially the women (this doesn't mean that I'll hate you less, only that I'll be more willing to hear your opinions, before telling you that you are an idiot)
Accept the fact that I'll never find a chick who is as smart, beautiful and fun to be with as my ex and settle for one who has 2 out of 3 of these qualities
Get back in shape
Start playing sports again
Spend less on gadgets and more on books
