Being smart is about making smart choices. Its about making the right decision, the right step or the right choice. Smart people move up the ladder real fast. They also are the ones that have great cars, lot of money, and everything else the rest of us desire.
One should be smart enough to know where to do the hard work in order to achieve the success or the desired goal. If everywhere you keep working hard and not getting results means their is some flaw in the system or in our self and we need to know that so exactly we can focus on our work and work hardly to achieve it.
