There is nothing rational about the idea that there is value to setting 3 or 5 year goals. Declaring something as a 3 or 5 year goal has no power to create a knowable future. Because of the constant of change, planning assumptions are largely reliable for about 2 quarters, at which point they need to be revisited and refreshed based on what's different. We accelerate change whenever we are dedicated to learning, innovation and mindfulness.
Goals of any timeframe are interests, directions we can move toward, one question at a time. The prime way to miss opportunities is to try working from planning assumptions, which is exactly what goals classically favor.
