We pursue exercise even though empirically we see no benefit from the energy we're spending and we're hurting. So empirically we should quit. The why is exactly the same thing. You persist even though there are some short-term stresses and even though there is some uncertainty.
I don't care what you do. We all deal with it if we're living life, trying to find those moments where you can turn off your brain and connect to whatever and just be grounded, live in the moment, which I find really difficult but try to practice on a daily basis.
