Between working hard and working smart; I will tell you that working smart is the best and it really pays. But most people don't know about this or don't believe in that ideology. They believe working day and night, leaving the office at late hour after everyone is gone is the way wealth. All that is just nothing but stress activators. When you do things the smart way; you stay healthy to enjoy the fruit of your labor but if the other way, the person might die even before the wealth start coming in.
Working hard is when you are doing a certain job in a company, putting so much effort, time, hard work and others. Yet, receiving just enough and not so high pay off supported by a statement saying "No one's ever get rich by working from 9am to 5pm". I would choose working smart and it is much better if you work smart with Bitcoin.
