Time
Too many things eating at my time. When I see something, I think about how much time that item represents. A video game can take 100 hours to complete, so it represents 100 hours of my life (assuming I finish it, which I wouldn't). The actual dollar amount I would pay for any item is nothing compared to the time I would spend with it. Assume some number of hours of live left, and from there one can work out the minimum percentage of ones life that item or event represents. If you are going to be hit by a car and die tomorrow, it represents a bigger part of your life.
So how does one decide? To many things calling out to me. "Spend time with me!" says the TV set. "Watch all of the shows. Sure, they might suck, but at least you will have something to talk about with other humans." "Eat me", says the Super Premium Ice Cream in my freezer. "Munch me.", says the snack food. "Come to me and spend the day.", says KFC. "Lick me from head to toe, stopping at some key locations to make sure you get the job done", says... well, I'll leave that one out for now. Then there is Internet Porn, "Look at all that I have to offer! Just 3 hours a day of your life is all I ask, and your every fantasy can be filled. Sex with plants, I've got thousands of movies and pictures for you." That Internet Porn, it always seems to know my weakness.
So, what is the point? Well, the price you pay for something is nothing compared to the time. You can make more money, but you can not make more time. So, stop watching bad TV shows, stop going to movies, don't play games, stop looking at porn (hold your horses until I finish before you think about lynching me for proposing this radical idea), etc - then you will have saved all of your wonderful, luscious time to do quality things, things that you really want to do... What else is there to do? If you give up everything, you have all of the time in the world, but the only thing left to do is sit around waiting to spend that time on something Really Big!

PS Waste your time how you feel, since even reading a classic book is still just wasting time. (or "using time" as an bloody optimist might say, those sad little people with nothing better to do that tell you that the glass is half full - well, I can tell them what to do with that other half of the glass! "Always look on the bring side.", what, so I can be blinded by their pithy sayings? "You can catch more flies with honey than vinegar", yeah, and they all drown slowly in the thick syrup, painfully suffocating, you sick "happy" bastards.) All things are equal in death. So, do anything you want, while you can. Even downloading plant porn.
