I like pithy sayings...sometimes called truisms. My family are surely sick of me repeating one or the other and have been known to roll their eyes.
As illustration, one good example is something occasionally attributed to Confucius: behind every crisis lies an opportunity. (One can also turn this around and say that behind every opportunity lies a crisis, if one screws it up). This saying has a number of corollaries, such as: if you are given lemons, make lemonade. It's a good way to turn a negative into something positive, if one is so inclined and takes the time. Of course, it's easier to merely moan about whatever the crisis might be. And, there are enough instances where it does not work: sudden death comes to mind.
I could add to this list seemingly endlessly (and will do so over time). I have even created a pithy saying of my own (although many have probably thought of this or something similar). I tell anyone that will listen: if you want to be on time, be early. Think about the wisdom of this statement...especially the chronically late amongst you. It is rather easy to avoid tardiness. I like to show up early; I prefer wait to the stress of rushing at the last minute. I learned this from years of air travel, when time needed to reach an airport and to navigate all the indignities inflicted by an airport were always difficult to estimate. Missing a flight was not an option, so I would arrive early and read. It's simply a matter of time management. People can think up any number of reason for being late, but there is no excuse.
