"Pick any two" triads

[Ken Ho]

You know what I mean. In business yo can be the best, the cheapest or the quickest, but not all 3 at once. Pick any two.
There is another.
I can train, work hard or diet to lose weight, but I can't do all 3 at once. At present I'm working, and really needed to rein on my appetite, so training is crap.

Everyone wants a cheap, light, low maintenance bike. Pick any two.

Everyone wants a cheap, light, low maintenance bike. Pick any two.

I'll take all three, at least when I had my fixies, it was cheap to build, light and very low maintenance. just the way a commuter bike should be.
