What has six faces, but does not wear makeup, has twenty-one eyes, but cannot see?

What runs around the whole yard without moving?

I can make you run, I can put you to sleep. I dictate your life I change every second . I follow your life. Stop me and I will never forget that time, you will loop back to that moment everyday, I will remain as a reminder to you of what you have done

I come in all shapes and sizes. A gun, a sword, a spear. I turn all men to children if my form is unique. Some people prefer me over automatic.

Some people use my name for a girl. I'm shiny and flat but round like a pearl. If you don't have even me, then you're very poor, yet some think me useless and make me no more.
