Sticky... think about the following (dubiously sourced) from an e-zine authored by Kal Bishop.
Motivation. Motivation is arguably more important than nature / nurture or traits. Someone with natural ability or placed in the right environment may not take advantage of it unless motivated. There is intrinsic motivation, synergistic and non-synergistic extrinsic motivation. How can it be induced and measured? There are many elements: material reward, progress to the ideal self, self-determination, self-evaluation, feedback, enjoyment, competency expansion, recognition and feasibility.
Blocks to creativity and organisational culture. What are the blocks to creativity and how can they be overcome? We can all be more creative, so what is stopping us? There are many blocks such as evaluation apprehension (in its many forms) and lack of adequate finance and resources. Separating creative from critical thinking, incremental productivity, tools that draw out tacit knowledge and using frameworks to trigger flow are some of the effective unblocking techniques. What is psychological safety and freedom? What properties of an organisational culture cultivate productivity?
