Mistakes

Think before you act. Usually it is best to count wits at a time. E.g,
1 wit. Move soldier
2nd wit. Attack
3rd wit etc.
Doing this will order your priority list, such as killing the enemy at the top of the list and lowering the "build medic ASAP" priority. Also performing multiple pronged attacks are good on your opponent. I once did a 3 pronged attack on glitch with a soldier, runner and heavy all near the enemies base. All he had was a heavy that could choose to attack my heavy and block his own spawn, save his wit space my killing my soldier or be silly and kill my runner.
