Keep your writing fresh and original

When I start to read something, I expect the writer to keep a promise to me, a promise the work will be fulfilling. That should be the reader outcome every time -the sense of being fulfilled.
One way of keeping our writing fresh and original is to avoid the use of cliches. I could tell you "the bottom line is, at the end of the day, when all the i's are dotted and t's are crossed, we don't want to be caught with our pants down or with a stiff upper lip or with the left hand not knowing what the right hand is doing - because the clock would run out on us."
But it will be a cold day in hell before I'd write anything like that.
