A good way to start your assessment would be to write down hobbies, and things you enjoy doing. After that, think in terms of which of these things can transfer into a pursuit where you can offer a profitable service. Last, but not least, think about what you'd like to do if you weren't getting paid. Whatever your business is, you're going to be involved in it day after day, so make sure it's something you're able to say you want to keep doing regularly.

Hope that helps, good luck!
