Hi Dutchy - I've worked for myself pretty much all my life. I've been deaf since birth and "doing my own thing" has always been easier than working in some environment like an office where, meaningfully or not, prejudice occurs. The advent of email was an absolute godsend to me.
The main piece of advice I would give is not to concern yourself with expanding too quickly. If you don't need a flash (expensive) office, work from home. The BMW can wait. Unless you really really need staff, don't employ them. Even a secretarial assistant will cost you
