Authentic happiness is always independent of external conditions. Vigilantly practice polite indifference to that which we can't control. Your happiness can only be found within.

In life our first job is this, to divide and distinguish things into two categories: externals I cannot control, but the choices I make with regard to them I do control. Where will I find good and bad? In me, in my choices.

Wisdom means understanding without any doubt that circumstances do not rise to meet our expectations. Events happen as they may. People behave as they will.

Nature hath given men one tongue but two ears, that we may hear from others twice as much as we speak.

If virtue promises happiness, prosperity and peace, then progress in virtue is progress in each of these for to whatever point the perfection of anything brings us, progress is always an approach toward it.

What disturbs people's minds are not events but their judgments on events.

When any person treats you ill or speaks ill of you, remember that he does this or says this because he thinks it is his duty. It is not possible, then, for him to follow that which seems right to you, but that which seems right to himself.
