I was drawn to the secret "Do the hard work needed to find a simple solution"
in my first mission. I can recall experiences where I have and have not done this.
I still recall the time as an undergraduate in a student project the time I refused to allow our group to go forward with a complicated solution to a programming problem - we spend the extra time refining and simplifying and improving up front and delivered a better system. This is still a lesson I have to remind myself of now and again,
I recall in a later professional life trying to solve the problem quickly. Which resulted in poor software that was hard to maintain, costing far more than spending more time upfront on the analysis to find a simple solution.
Keep it Simple Stupid. (It will also be elegant, beautiful and something to be proud off)
