Well, I used to be a furniture designer and maker full time. I showed, and still show my work in galleries and the like, and continue to build to order when I feel in the mood and the price is right. There are advantages to being an amateur I've discovered-- such as being choosy about what work and clients I take on.
I closed my business in the US to move back to the UK to take up a job offer teaching the subject full time-- there's only so much of life in America a full blooded Brit can take, ha, ha.
Now I do designing and making on the side to suit my full-time work, and write articles on the subject from time to time.
I often think that being a self employed designer/maker is easier than teaching. It's almost certainly less work.
But I do get a real kick when a student 'gets it'. Slainte.
