A Machine Called Life

Im just starting out..please review and let me know what you think.Thanks!

On this beast called life I ride
Filled with fear and with pride
I try to avoid the claws and teeth
So I don't become a tasty treat

On this machine called life I ride
Tickity-tock it keeps great time
I try to avoid the gears and wheels
The ones that don't, you'll hear them squeal

A machine called life
