Variety is when you repeat the same things over and over again. Simplicity is when you repeat the same thing over and over again. Trying new things is when you don’t repeat anything over and over again.
I appreciate simplicity and trying new things. I don’t appreciate variety as much.
For instance, I usually order a completely new meal at restaurants (trying new things), or the same one I always get (simplicity). And I usually wear the same basic set of clothes (simplicity), unless I’m introducing a new item (trying new things).
I don’t usually rotate through a bunch of different meals or a bunch of different clothes only to return to the same ones again (variety).
The idea is that if everything else stays simple and reliable, it’s easier to add new things. It’s easier to experiment when the control group is already set.
