Let me assure you that, having gone through a very major health crisis, stoicism is eminently useful, and practical. I have lost things that are impossible to recover. And I'm doing pretty good, thanks.

There are some things you really cannot change. We can change more than we used to, but not everything. Stoicism helps.

And we also change things we don't need to change. We chase after things that bring us no happiness. By allowing you to be happy with what you have, stoicism lets you seek those things that truly matter.
