Is your true professional desire and passion - your 'true north' - to succeed in business? Or, would you rather be doing something else - be an engineer, doctor, artist, writer, trader, craftsman, etc.? Desire is a person’s need to possess or achieve something. Think of it as the engine at the front of a train pulling it. If you desire something, you will pursue it with vigor. Obviously, if your desire in business is low, you may quickly lose interest; if it is high, your interest may be sustained for a long time. If you are passionate about business, your interest could last a lifetime.
