I've now been working for over a year now.

Top 10 things I've learned from my first full year of work:

10) Some people aren't very good at replacing the water cooler.
9) Check your mug every now and then. See my post on August 9th.
8) When moving an important document, copy and paste it, instead of cutting and pasting. See my post on May 4th.
7) I now understand why people are so dependent on coffee (fortunately, that's not me yet.)
6) There are more people who are vegetarian than I thought.
5) Co-workers are much funnier when they're drunk.
4) Nobody really cares if you waste time at work, as long as you get your work done.
3) If there's free food available, people will eat it. No matter what it is.
2) Sit in the back during seminars, or drink lots of coffee.
1) In many tropical countries, people have siestas, where they take naps after lunch. America needs siestas.
