Steven,
As above about marketing plus this...
This may sound crazy.
I know two self made millionaires. Both have said that when you start a business, you should have a clear plan on what you want out of it and more importantly, how you intend to get out of it.
In other words, are you thinking of building a business to sell later or are you building it to say, pass on to your children? If you are sure about which way you are going it's easier to plan the next couple of years.
