You can’t teach a pig to sing. It’s a waste of time and it annoys the pig.

Use it up,
Wear it out,
Make do,
Or do without.

There are hundreds of paths up the mountain,
all leading in the same direction,
so it doesn’t matter which path you take.
The only one wasting time is the one
who runs around and around the mountain,
telling everyone that his or her path is wrong.
