The excellent Adliterate is often talking about the wonder of good aphorisms.
I noticed yesterday that BDO Stoy Hayward have been doing a series called 33 Thoughts, featuring interesting and funny business related proverbs.
Some great examples:
"Money won't buy happiness, but it will pay the salaries of a large research staff to study the problem"
“ If I had to live my life again, I’d make the same mistakes, only sooner ” Tallulah Bankhead
"The secret of success is honesty and fair dealing, if you can fake those you've got it made."
There are some fantastic ones, along with real useful business thoughts.
I wholeheartedly recommend you spend some time there.
