The Artist's Development Toolkit is perfect for someone who already knows fairly well what he is doing and where he is heading. It helps in organizing ideas, in realizing the roads that still remain under-explored, and above all, in looking at the (mainly production-based, not artistic) obstacles in your career in a cool, distant way. All this through a self-help methodology. You answer questions, than you read your questions and get some suggestions on how to analyze them. (Don't forget to click on the little "+" signs, they give you extra info that is often much better than all the rest).
To someone really confused, it might bring only despair. It doesn't give answers, doesn't guide you. And we're not talking artistic guidance, but production, career guidance.
It is also an extremely long process. For the patient ones.
So if you're patient, not too lost, not too desperate, if you have a specialized field you're working in, a public, if you pretty well know where you are heading, this may help you. If you really, really need help, then maybe it's better you go and get some - and maybe use this as additional support.
Let me know how it worked out for you!
