I want to own a house, without having to take up a loan from the banks. Here me and my girlfriend can have kids and we can all live in the house. I want that the company I own earns so much money that I can be comfortably confident that my company can pay me a pay check for decades without further reliance on others. This will leave me free to experiment and create things as I see fit. I want that some of the things I make gain a whole bunch of customers, so that I can hire other people to work on more things. At the moment my income comes from contracting for another company. I like working for them as well, and want to work for them for the foreseeable future. The other things I mention above are long term goals, and I am building towards those goals.
