The more coffee you drink, the less sleep you need. I just had a great business idea. I could rent out your bed, and with the money you’d make off it, you could buy enough...

Here’s what I’d love to see: A vending machine that dispenses cats for petting on your lunch break. Instead of money, the machine accepts hugs.

I’d like to invent a product that’ll turn 18-year-olds into 21-year-olds, and sell it in front of bars.

Business ideas are like those flying dragons in Avatar. First you have to find one, let it choose you, then be brave enough to ride it.
