I am regularly asked, 'Should I get cards printed?' What a difficult question. Just that they asked tells me they are thinking about hanging their shingle to represent themselves as a professional. My usual answer is why do you think you need business cards. This is where you need to stop and seriously, is this what I want? Why do you think you're good enough? Is it because mom & dad tell you how good you are? What makes them an expert?
Unless you have blunt parents, all parents think their child is good at whatever they do. Same for Aunts and Uncles, don't put a lot of stock in them either. Usually your peers will be the best judge. Before stepping over the line, step softly and cautiously. Know you niche, keep your products small and as your abilities grow, grow your products, DO NOT take on jobs you do not know what you are doing. Praises expand outward slowly, screw ups get around at super sonic speed and sometimes takes years to live down.
