Imperfection can yield positive results...

Imperfect results help to remind one, that one is not the absolute source of perfection, and that one shouldn't expect to gain 100% perfection through any action they attempt, as they will be doomed to fail.

Inefficiency is attempting to achieve a goal that is doomed to never be realised.

Of all the things that rise and fall,

None of them contain anything of real interest.

Whatever interest they do pay out,

Always ends in debt.
