A pupil once asked me why I tried so hard to do things well. After all, one of the bases of Stoic philosophy is that nothing is really under our control, other than our mind — specifically, our willpower, and the decisions we make.
Believing this does not mean, however, abdicating responsibility. What gives us responsibility for our actions is our intention, not the result.
Our job is to roll the dice. How they fall, that’s for the fates to decide.
Toss them well.
