"Time keeps moving on and on and on, soon we'll all be gone." - Blink 182

Face it. We will all die eventually, so why not make life worth dying for? You are constantly moving forward in time, and leaving all the minuets and seconds behind. You should make all those minuets and seconds add up to a greater picture. This picture will be you in old age, looking back at your life... and being happy with it. Live all your moments with that future in the back of your mind. Think "will this make me pleased with my life? or "will i be proud of myself when i'm older?". With this in mind, go forth and have fun. Make mistakes and laugh about them when you tell your friends and family. If you are enjoying your life, you will be happy in youth and old age.
