Observe CAREFULLY

Look at people carefully (but not starefully) when analyzing them.
Don't jump at conclusions. We humans have a great way of twisting facts
to fit our conclusion as soon as we have made one. But don't spend all
your time getting ready to decide and forget to decide at all, like the
man who was going to jump a ditch. He ran so far back to get a good
start each time that he never had the strength to jump when he got
there. Get a good start by observing carefully. Then

Decide CONFIDENTLY

Be sure you are right and then go ahead. Make a decision and make it

they were built to be used or you will get little service out of them.

You would not expect to run a car properly without paying the closest
attention to the rules for clutches, brakes, starters and gears.
Everything scientific is based not on guesses but laws. This course in
Analyzing People on Sight is as scientific as the automobile. It will
carry you far and do it easily if you will do your part. Your part
consists of learning the few simple rules laid down in this book and in
applying them in the everyday affairs of your life.
