What's the difference between a self-employed and an entrepreneur? Well, whatever the difference is, you don't have to choose between the two. With technology, you can do the work and still earn money while you slept.
One skill all good entrepreneurs must have is empathy. Having empathy doesn't just help you see things from the frame of reference of your attitude. Having empathy also helps you win. And sometimes having empathy is the reason why you'll succeed when others failed.
