Any beginner is apt to have "buck fever," and therefore no beginner should go at dangerous game.
Buck fever means a state of intense nervous excitement which may be entirely divorced from timidity.

It may affect a man the first time he has to speak to a large audience just as it affects him the first time he sees a buck or goes into battle.

What such a man needs is not courage but nerve control, cool-headedness.

This he can get only by actual practice.

He must, by custom and repeated exercise of self-mastery, get his nerves thoroughly under control.
