Keep your hands in your pockets, you marketers

They say you have to lay out some money to make some money - but first you have to learn where to invest it.  The great thing about working online is that the overheads are peanuts compared with a conventional business, and it really is possible to start up on a shoe-string budget.  Trouble is, it is a great big market place, full of people trying to sell you products to help you succeed in your business.

A great piece of advice I read said 'Stop being a buyer, and become a seller'.  That's it, you have to cross that line.  But, of course you want some information to help you along the way.
