You'll have to unlearn all you learned before you can get right down to human nature, and unlearnin' takes a lot of time.

Some men can never forget what they learned at college.

Such men may get to be district leaders by a fluke, but they never last.
To learn real human nature you have to go among the people, see them and be seen..1 know every man, woman, and child in the Fifteenth District, except them that's been born this summer--and I know some of them, too.
I know what they like and what they don't like, what they are strong at and what they are weak in, and I reach them by approachin' at the right side.
For instance, here's how I gather in the young men.

I hear of a young feller that's proud of his voice, thinks that he can sing fine.

I ask him to come around to Washington Hall and join our Glee Club.
