Nothing truly stops you. Nothing truly holds you back. For your own will is always within your control. Sickness may challenge your body. But are you merely your body? Lameness may impede your legs. But you are not merely your legs. Your will is bigger than your legs. Your will needn't be affected by an incident unless you let it.
EpictetusAppearances to the mind are of four kinds. Things either are what they appear to be; or they neither are, nor appear to be; or they are, and do not appear to be; or they are not, and yet appear to be. Rightly to aim in all these cases is the wise man's task.
