When you do things that you know the outcome of, there’s no reason to worry. You already know that you’ll achieve the outcome.
Worry sets in when you pursue something with an uncertain outcome. The greater the uncertainty of the outcome, the greater the worry.
Looking at things this way, doing things with relatively certain outcomes is an easy way to avoid worry.
However, those things with relatively certain outcomes also tend to be less meaningful. Those things that are worth doing tend to have uncertain outcomes.
So the choice is between doing meaningful things with uncertain outcomes and hence worry, and less meaningful things with relatively certain outcomes and low worry.
There’s room for both. However, most of us naturally gravitate towards the latter in order to minimize worry. Reminding ourselves that the former produce worry for a good reason helps us do more of these things.
