I agree, creativity and freedom to do what you feel/want are very connected. However, if the project is large enough, self-control and discipline is required to turn that project into something great, especially for entrepreneurs who wear many hats.
I agree. Creative and brilliant ideas can come at anytime, but putting in the work to get those ideas to market, or to polish them off until presentable to outsiders is where the disciple comes in.
I can wake up in the middle of the night with a great idea to improve a UI workflow, or to squeeze more performance out of a process, but if my disciple doesn't kick and I write the code to get it done,
Also it doesn't take intelligence to makes sure my Press page, About page and Resume stay current, it just takes discipline.
All of my prior jobs have been given to me based on my completed portfolio projects, not on my great ideas. And numerous co-workers have been let go because their brilliance never results in 'finished' projects.
