When play becomes a job, it eventually becomes work. There are times, no matter how much we love and enjoy what we do, that we don’t want to do it. We must have the fortitude of willpower to work through those times.
We eventually must reach a stable point where we can reevaluate what is making us miserable.
In other words, we love the work we do. And when we no longer love it, we change it or move on.
