I think constraints are key to innovation, and so I think the very first secret is the most interesting and important to me. Constraints are what force us to think outside our normal routines, and working within unfamiliar parameters makes us do unfamiliar things. In my own experience, my best ideas often come as a result of doing unfamiliar things, whether they be in creative ventures, travel, or solving problems. So if I'm working in a constrained environment, I won't despise the constraints. I will embrace them. I will work with them, and try to see them not as obstacles to success, but rather as building blocks of innovation.
