Are we in balance? Are we ready? Have we taken care to do our work at a steady pace? Will we move quick enough to get things done on time, and slow enough to see obvious oversights?
The fighter who prepares the best is usually the fighter that wins.
And the best way to prepare is to accept that a bunch of unexpected stuff is going to happen. That way you won’t be jolted so easily by a curveball or foul play. And so the unexpected becomes expected.
