Cliche Confusion

They say "money makes the world go round" I really don't understand I thought it was a magnetic field not something made by man They say "don't count your chickens before they begin to hatch" but what if my eggs came........... from a totally different batch? They say "what goes around comes around" I'm just a little bit confused How can I use the same fire cracker when I already lit the fuse? They say "what goes up must come down" but what if its in outer-space?? Does Newton's law of gravity come back and smack us in the face?? They say "a way to a man's heart is through his stomach" This seems like a very hard task, and isn't it true to reach the stomach the heart at first you must pass??? They say "beauty is only skin deep" what does that really mean? Is it because we bathe with soap that our pores are really clean? All these quotes and cliches and the all around play on words got me all confused I think its just absurd But I can't blame anyone I can only blame myself I should of picked up the thesaurus thats been sitting on my shelf
