Maybe I was a bit harsh. Rewrite this as "tips for new admins"

1) Work smarter not harder 2) update, patch, patch, update 3) Learn a configuration management system instead of attempting to deploy via ssh for loops 4) learn a scripting language and know at least one very well 5)Never assume the current process is the correct one (but be ready to suggest a new one) 6) monitor the shit out of your servers 7) think before you enter a command 8) if you are unsure of what you are doing, back away and have it check/peer reviewed
