The materials of action are variable, but the use we make of them should be constant.

Circumstances hand you different material every year: more money one season and less the next, good health then poor, an easy job then a hard one. What you do with the material is where you actually live. Someone can be decent when flush and decent when broke, careful when praised and careful when ignored, and that steadiness is not luck in the circumstances but a constant applied to whatever arrives.

Look at how differently you behave when things go well and when they do not. Choose one behaviour you like in the good version of yourself and keep it running through the bad version, even in a reduced form.
