Let me start by saying that smart work and hard work are not mutually exclusive. Neither does it mean that they are one and the same.
The fact is that any strategy may employ a smart or even a genius level work around to a big problem and yet it would also mean that to execute that strategy, hard work might still be required. The thing about smart work is that it is focused and uses creativity as a means to obtain the objective by using 'hard work' as one of the tools.
Some of the most efficient strategies may still end up draining our mental and physical resources. What I mean to imply is that there is no way to choose between hard work or smart work because in most cases they both are required to achieve ones goals.
