The thing about powering through, is that keep doing it, and you end up having to keep powering through everything as your health collapses. Before long you end up like Elvis trying to power through a shit, and then you realise you're going to die on a toilet.
Back away from the the powering through mentality. It's just for the most loyal of self immolating slaves really. You can at least choose to be a lackadaisical slave, as a bare minimum.
