Don't make your training about unnatural stunts that impress people. If you do that, you're no different from circus performers — even though you call yourself a philosopher. Walking on a tightrope is hard and dangerous. Should you practice tightrope walking because of that? Should you practice climbing palm trees or hugging statues? Of course not. Just because something is difficult and dangerous doesn't make it good practice. Good practice is what helps you achieve your actual goal.
We ought not to make our exercises consist in means contrary to nature and adapted to cause admiration, for if we do so, we who call ourselves philosophers, shall not differ at all from jugglers. For it is difficult even to walk on a rope; and not only difficult, but it is also dangerous. Ought we for this reason to practice walking on a rope, or setting up a palm-tree, or embracing statues? By no means. Every thing which is difficult and dangerous is not suitable for practice; but that is suitable which conduces to the working out of that which is proposed to us.
