The road to sustained profitability for a business is not only about sticking to a strategy or business model (even one that has been profitable in the past). It is also about surveying and reacting to the changing landscape. Similarly, for each of us on an individual level, the road to happiness is not in sticking blindly to the thing that we’re doing, as so many aphorisms cajole us to do. We need to see what’s going on around us so we can do whatever will maximize our happiness and our time and our well-being.
