...one of the smartest guys I've ever met taught me something once and time and time again it's proven itself useful, so I thought I would share.
When presented with a problem, if you haven't thought of three ways to solve it then you haven't thought hard enough - it probably also means that you don't understand the problem well enough.
That thought is powerful for a number of reasons: it forces us to look at a problem in original ways as we try to get to that "third solution", it forces us to understand the problem (face it, you probably don't understand the nature of the problem if you're just copying someone else's solution), and it forces us to question what
really is the problem as understanding the nature of the problem always reduces the 'noise' around it.
....this tactic just saved my can a couple minutes ago as I suddenly saw through a problem on the third 'way to solve it' that I had missed earlier.
