They say hard work is the one way to success. True, but there's a catch. You don't have to just work hard, you also have to work smart. As Caterina Fake once said, ''If you’re working on the wrong problem, it doesn’t matter how hard you work at it''. Remember to combine working with thinking. That’s what your head is for.
