Have you played the Two Things game?
According to Glenn Whitman, it's based on the assumption that for every subject, there are only two things you really need to know. Everything else is the application of those two things, or just not important.
Some of my favorite ones...
The Two Things about Software Engineering
1. There is no such thing as bug-free software.
2. Adding manpower to a late project makes it later.
The Two Things about Web programming (as it is mostly done in the real world)
The Two Things about Biology
1. Evolution is the process through which genetic structures that are better equipped to reproduce viable copies will tend to proliferate.
2. Except for the Platypus.
The Two Things about Medicine
1. Do no harm.
2. To do any good, you must risk doing harm.
The Two Things about Civil Engineering
1. Dirt + Water = Mud.
2. You can’t push a rope.
So next time you meet someone who has a different occupation from you, or who knows something about a subject you are unfamiliar with... ask them about The Two Things.
This meme caught my eye when I stumbled across it on the Interwebs today, because right at the end of my recent trip to Cabarete to spend 5 days trying to improve my Laser sailing, someone explained to me The Two Things about Laser Sailing. But before I reveal this secret, I would like to hear in the comments what you think are The Two Things about Sailing (or about whatever other watery perversion you favor.)
Go for it.
