There is one thing you can always believe true. There is nothing or no one you can truly count on. Even you deceive yourself.
Be constantly alert and never underestimate what is possible-good or bad-in any situation. Never assume that what appears to be, is actually what it seems to be.
Any assumptions that you make about always being in control is usually only an illusion, a form of deceiving yourself. When everything is going along smoothly and there is nothing wrong, there is nothing wrong, except, there is nothing wrong.
Mistakes are made continuously, no one or nothing is perfect. If it is running too smooth what is being hid from sight/detection? Trust your instincts to perceive things which cannot be seen, face the facts, and then deal with them.
