Keep Your Butt in the Chair!

But preparation of this sort for the pulpit is not easy. It requires time, self-conquest and hard work. Perhaps the greatest ministerial temptation is idleness in study--not in going about and doing something, but in finding and rightly using precious hours in one's library, avoiding reverie and light or desultory reading, and sticking hard and fast to the Sabbath work.
