What is time?

Do you ever wonder how time works? Where does it go? It seems to go so slow at times and so fast at others. They say "time flies when you're having fun". This statement is probably one of the most true statements you will ever hear. When you are on vacation, at a party, spending time with friends, etc. you lose all track of time and before you know it's time to go home, the party is over and you're back to your everyday routine. This is all because you're having a good time and enjoying life! Which makes me wonder can we do this all the time? Even while going about our day to day life? Of course its still not going to be quite as much fun as a party, a vacation or just hanging out with friends but why shouldn't you have fun everyday too? So the next time you are going through the motions and feel that time is just dragging add a little fun and see how much quicker time starts moving.
