It is useless to contend with the irresistible power of Time, which goes on continually creating by a process of constant destruction.
It's not worth doing something unless you were doing something that someone, somewere, would much rather you weren't doing.
Doing a thing well is often a waste of time.
There is no problem that is not improved by effort, and no effort that is too paltry to be worth undertaking.
Anything that is wasted effort represents wasted time. The best management of our time thus becomes linked inseparably with the best utilization of our efforts.
The most useless are those who never change through the years.

It is better of course to know useless things than to know nothing.
Only useless things are indispensable.
Just because something doesn't do what you planned it to do doesn't mean it's useless.
