Creative types should check out the Accidental Creative podcast, especially #22, "who are you? really?!?," which talks a lot about being authentic as an artist and silencing those pernicious Inner Critic voices we all hear, especially things we got from our parents about "being practical" vs. making art. It's useful, real, and well-organized, without being stupidly cheerleadery or useless.
The 'casts tend to average around ten minutes, and while there are occasional "advertisements" for the website's e-coaching services, this does not distract from or reduce the usefulness and sincerity of the advice of the podcast. Other subjects include learing from rejections, time-management, and finding your own voice.
All artists and creative types, from the rare good managers in the business world to painters or writers, will find something to use in every single podcast, whether you usually like "self-help" sorts of things or not. The Accidental Creative is not your usual self-help resource for artists. It is very much, as Todd Henry himself calls it, "rubber meets the road" stuff--immediate advice you can use today, and thought-provoking input that will help you spend your creation time wisely and effectively. None of us have enough time to create; use this podcast to help you make the most of it.
