Fortunately there is a very considerable amount of work in which new circumstances call for new skill and a man can go on improving, at any rate until he has reached middle age.

Context

“If these conditions are absent, it will cease to be interesting when a man has acquired his maximum skill. A man who runs three-mile races will cease to find pleasure in this occupation when he passes the age at which he can beat his own previous record. Fortunately there is a very considerable amount of work in which new circumstances call for new skill and a man can go on improving, at any rate until he has reached middle age. In some kinds of skilled work, such as politics, for example, it seems that men are at their best between sixty and seventy, the reason being that in such occupations a wide experience of other men is essential.” source
