Pressure. if only it didn't exist.

Off topic: LOL. I think pressure is when molecules collide with each other and the container...
On topic: I think pressure helps you learn leadership and other qualities needed for life....

Pressure = force / area.

On topic, say the one thing you really want to do in life is, iunno, hang gliding (random thing that came to mind). You're fed up with the pressures of society because they want you to study well, go to college, and get some high paying job. You wish you didn't have to study so you could hang glide all day, right?

However, if no one at all was pressured to do well, no one would feel the urge to rise to the top, no one would build factories for manufacturing raw materials, no one would work in one if it existed or organize the workers if they existed, no one would bother inventing newer, safer models of hang gliders because they wouldn't get built, no one would bother educating people on how to hang glide safely because hang gliders don't exist, and no one would operate the stores that would sell them if they did exist.

No one gets satisfied, and everyone just slacks off and dies off.
