The problem with doing hard things is that well, it's hard.
It's a romantic notion, sure, but in practice? It can be kind of terrible.
I mean, who wants to wake up with their stomach all in knots? Who wants to risk failure or embarrassment or...well, really anything at all?
There is a reason, after all, that we have not done that hard thing already.
There is no reason, in many cases, that we have to do that hard thing at all.
So to choose it? To choose challenge, sacrifice, interruption in mere hopes that in the end, it will be worth it?
