I think there are different kinds of smarts, and ultimately it comes down to your goals. Someone who is a mathematical genius may not be 'smart' with their money, and could end up broke.
I think we need to be both smart and strategic person at the same time. Being smart without wise strategy is not much effective. I believe that it would be easier for us to do things in a smart ways if we have strategies and techniques to be able to do things better.
