John Williams's shiftsurgery

The key to success for you is to find a way to focus your time and energy on what you're best at - creating new stuff - and collaborate with others who will keep you tuned into the market and find you funding to leverage your creations.

This is not a question of "Should I be an artist?" but "How do I make this work for me?". So the question becomes what do you do in order to be able to create your art and make a living - even if the two things have to be separate at first?

I must say I'm not a great fan of transferable skills and core competency lists. Think broader than "skills" - maybe you're a natural networker, a great systematiser, a killer dealmaker, or brilliant at generating bags of new ideas (even if you never follow through on any of them). All of these things are of value in the workplace if you know how to use them.
