To Swap

In "Words with Friends" you have to know
Exactly when to swap,
For sometimes with the tiles you have
You can't come out on top.

The same is true in life, I guess;
At times we have to trade
Our car, our job or maybe spouse
Before our chances fade.

I mostly hold my letters, though,
And rarely make a switch,
Since upgrades are among those things
For which I have no itch.

I play with three opponents
And of course I lose a lot,
Perhaps because I mostly tend
To stick with what I've got.
