If you have a meeting at 3:30pm, be there at 3:29 :)
It sucks when people don't follow time. A lot of my friends can attest to this belief of mine. I hate being late. I really really really hate it. It sucks being punctual though.
If you'll be late, have the courtesy of informing the person who will wait. It makes a big difference! :)
So if you have a resolution for 2010, I highly recommend that you be PUNCTUAL :)
