A hobby is not a holiday...

A hobby is not a holiday. It is not merely a momentary relaxation necessary to the renewal of work; and in this respect it must be sharply distinguished from much that is called sport. A good game is a good thing, but it is not the same thing as a hobby; and many go golfing... because this is a concentrated form of recreation; just as what our contemporaries find in whisky is a concentrated form of what our fathers found diffused in beer. If half a day is to take a man out of himself, or make a new man of him, it is better done by some sharp competitive excitement like sport. But a hobby is not half a day but half a life-time. It would be truer to accuse the hobbyist of living a double life. And hobbies, especially such hobbies as the toy theatre, have a character that runs parallel to practical professional effort, and is not merely a reaction from it. It is not merely taking exercise; it is doing work.
