Talk to people. Find out from other people who are doing that work, something similar, what its like. Ask them for pointers, talk to them, engage. Its almost like networking, I guess it is networking. Talk to people who have done it. I thought I knew what I was getting into, and for the most part I did, but there were key elements that I was missing that slowed me down. You may find that the experience wasn't anything like you wanted it to be. You may find that its exactly what your are hoping it is but you have to take certain steps to make sure your not going down the wrong path. It's like any other business once you go down a path its hard to back track and start over, or redo even part of it. Talk to people who have succeeded, who are running their own business. Ask them about building a network, acquiring clients, marketing, the legal aspect. Get advice. If you haven't done it before you don't know what you don't know. If you don't exactly how to do something of the things you will find out, at least you know where you are on the landscape and you can plan accordingly.
