Decide not rashly. The decision made
Can never be recalled. The gods implore not,
Plead not, solicit not; they only offer
Choice and occasion, which once being passed
Return no more. Dost thou accept the gift?
Every art and every inquiry, and similarly every action and choice, is thought to aim at some good; and for this reason the good has rightly been declared to be that at which all things aim.
We really are living in the era that all this sci-fi literature and cinema was centered around, but it's not anything like what we envisioned it to be. It's almost like there's too much choice.

I have a few minor rules for myself but I break them all the time. For example, when translating from Romance languages to English, there is often a choice between a Latinate cognate and a Germanic equivalent. An easy example would be the Portuguese escuridão: English offers both obscurity and dark or darkness, and some translators will tell you the Latinate word is generally reserved for poetic and figurative expressions, while the Germanic word is used for colloquial and idiomatic use.
