Assume I am completely naïve about boating concerns, that I know the following:
There are things that float and carry stuff across the water called boats.
A boat needs something to make it move. Some have sails.

Sails seem like they might require less effort than paddles and don't have the fuel or other complications of motors, so let's assume sailboats for this question.
What are the things I should know (or do, or get, etc.) before clumsily rushing into sailing?
