Let us think of everything that can happen as something which will happen; as such, it is indeed foolish to be unhappy now because you may be unhappy at some future time; Hence, allocate a time for worries, & free your appointment for happiness.
Although your conscience makes you confident, yet, since many things have weight which are outside your case, both hope for that which is utterly just, & prepare yourself against that which is utterly unjust, as such prepare for the worst & hope for the best.
We should strip the mask, not only from people, but from things, & restore to each object its own aspect; seek to truly understand the core principles & fundamentals of things.
