Work Hard and Regularly Stay Updated in Your Chosen Career.
Whatever industry you choose either you work as a manager in an office or as a sales person or as a start- up entrepreneur, you should be able to outwork everyone. I was watching a show and in the speech given by Mark Cuban he said and I quote:
The periods you spend procrastinating, there is someone who is working extra hard to take that position from you, a person who works extra hard always gets on very important opportunities.
