“Expect the best, plan for the worst and prepare to be surprised.”
“Expect the best, prepare for the worst.”
“Hope for the best, plan for the worst, but also try to be prepared for the unexpected.”
“Expect the best. Prepare for the worst. Capitalize on what comes.”
“‘Expect the best, but prepare for the worst.’ I'm good at the first part, crap at the second.”
“This is the precept by which I have lived: Prepare for the worst; expect the best; and take what comes.”
