Rule 1: Life is like an onion: you peel it one layer at a time, and sometimes you weep. So is programming.
Rule 2: Internet is one of your most reliable friends.
Rule 3: Whenever encounter a problem, search on Internet, refer to books and think. Until you know exactly what the problem is, don't ask for help.
Rule 4: Don't bother (ask tech questions etc.) colleagues too often. People are all busy!
Rule 5: Taking notes is very very important. If you have a doubt, read Rule 1 five times.
