As leaders, sometimes we become so focused on pushing others, that we forget to push ourselves. Being self-disciplined and willing to push yourself is a key attribute of successful leaders. And especially successful entrepreneurs.

Don't be like a wheelbarrow, that only goes as far as it is pushed. If you are relying on someone else around you or above you to push you to get things done or to grow as a leader, it's time to step up and push yourself.

Someone once said: "There are three kinds of people in this world. Those who MAKE things happen. Those who WATCH things happen. And those who say 'WHAT HAPPENED?"

Which kind of leader are you?
