Because the truth is, no matter what you do you're going to end up working really hard. You are going to work hard. So why not stack the odds in your favor and do something that you love. And no matter what you do, there are going to be tough days. Everybody has tough days.
Doctors have tough days.
Social workers have tough days. Poets have tough days, even ice cream men have tough days. Sure they're outdoors and playing with kids but you listen to Edelweiss 14,000 times a day on the bells. Even guys who have no jobs, who just sit around and around and watch TV, they have tough days. The cable could go out.
