This is an inspirational article, Bill - quite simple, direct, actionable and profound. I always wanted to write and am finally channelling my inner mojo to get down to it, find it totally rewarding already.
Really admire your implicit perspective of focussing on engagement, fulfillment and freedom and accomplishing it by using the power of "deadlines".
I published an article a few weeks ago on a similar topic based on learnings from Daniel Pink's excellent book "Drive". Big takeaway: creativity is painful and the “carrot and stick” approach hinders it. Somewhat contrary to your advice, Pink says that nurturing and cajoling our intrinsic motivation leads to enhanced output and satisfaction, but when bound by time-pressure, creatie tasks suffer. Titled "Unlock Your Inner Mojo" - would really appreciate your feedback on it!
