one of the things that really bugs me is how many practitioners do not what it takes to have a successful business. They concentrate on their therapy and often leave the marketing side to take care of itself.
No wonder many practitioners aren't very successful. On My Therapy Practice I have a look of articles in the running a successful practice section designed to encourage practitioners to be more business-like.
I've just added a great one from Sean D'Souza on business card design - he writes in a humourous way but makes clear points about what is and is not good business card design.
Take a read - what he says doesn't just apply to therapists but is relevant for anyone who is thinking of having business cards made.
