Keeping track of the things I want to do, and the things I actually get done, is a way for me to encourage myself to expand and diversify my experience by enjoying life.
My mother always told me that I should have a goal, even if that goal might change a number of times as I try to reach it. It's always better to be moving forward in some direction, than sitting at home with no direction at all.
My bucket list is on this website so I can check it from almost anywhere in the world, and so that I can show it to friends or strangers if I feel like sharing.
