Dan Meredith reveals this strategy of how to deal with people that you want to smash.
Every time you get annoyed at someone, write him a very aggressive email, telling him what you think and why you are pissed off.
Use all you anger to write it down.
But don’t send it! Keep it for the next day.
The thing is, if you sleep with it, the next day you will not want to send such an email, and you will write a much nicer and collected one.
