Assumptions can get you killed. --Titus Ray, Chapter 2

When we constantly react to assumptions and hearsay, bad things happen.

Assumptions can subsist on a foundation of quicksand.

We work too much on assumptions in times of desperation; until proven wrong, we are adamant and disobliging.

Once assumptions are set in play they tend to justify additional assumptions.

Assume things are more complexed than they appear on the surface.
