Do not disturb your life!

Marcus Aurelius - Book 8: pg.47

Do not disturb yourself
by thinking the whole of your life
let not your thoughts embrace all the troubles
that you may expect to befall you

But on every occasion - ask yourself-
what is there in this - which is intolerable?

for you will be ashamed to confess!
next,        remember that neither past nor the future - pains you
but only the present

but this is reduced to very little if you circumscribe it
and chide your mind, if it's unable to hold out against this!
