24. Embrace the suck
This one is very useful for dealing with rebellious teenagers whining about their chores. In armed forces, people are taught early on to embrace the suck, meaning that a large portion of their enlistment will be spent doing unpleasant or simply boring stuff, which needs to be done with as little complaining as possible. For every minute of shooting or blowing things up, there are at least nine minutes of soul-crushingly dull presentation or cleaning the latrine. There is no way of getting out of it, so you might just as well enjoy it, according to drill sergeants. So, embrace the suck and keep shoveling the snow.
