I'd like to go by climbing a birch tree~ And climb black branches up a snow-white trunk Toward heaven, till the tree could bear no more, But dipped its top and set me down again. That would be good both going and coming back. One could do worse than be a swinger of birches.
To put yourself into a situation where a mistake cannot necessarily be recouped, where the life you lose may be your own, clears the head wonderfully. It puts domestic problems back into proportion and adds an element of seriousness to your drab, routine life. Perhaps this is one reason why climbing has become increasingly hard as society has become increasingly, disproportionately, coddling.
We seldom break a leg as long as we are climbing wearily upwards in our lives, instead we do it when we start going easy on ourselves and choosing the comfortable paths.
