On a much lighter note, Guy Browning's "Never Push When It Says Pull" gives you advice on the more mundane tasks we face, such as ironing, hiring a car, and using a lift (if you don't know what a lift is, see here):
Calling a lift is easy. Simply press the button and wait.
And then press the button again. Many lifts work on
the pressure you exert on the call button, so hitting it a
hundred times will make it arrive a lot faster. Before you
get into the lift, it’s as well to check whether it’s going up
or down. There’s nothing more embarrassing than
saying confidently to a packed lift ‘Ground floor please’
and then feeling the lift rocketing upwards.
