I highly agree that you should definitely research the law before packing your bags and heading for Bangkok to just start bootstrapping.
As hackerboos mentioned, it is illegal to "work" here without a work permit. As I understand it, even with a work permit, you're only allowed to "work" at the place that is specified on your work permit and no where else. If you are caught working outside your permitted working location, you can be deported.
It all sounds very harsh but I assume that this is often the way labor laws for foreigners are written by most countries; the main goal is to protect the local work force from unfair outside competition... that's just how it is.
