Never Lose Your Passion!
Passion is the great equalizer. It can make up for a lack of experience and knowledge. I am not suggesting that you not develop your knowledge or experience - only that until you do, your passion will be interpreted by others as a strong belief in yourself, your mission and your purpose.
Passion is different from enthusiasm. The old outworn cliché says "Act enthusiastic and you will become enthusiastic." I have never subscribed to this philosophy. The reason is that if enthusiasm is an act which you use when things are going well, how do you behave when your life is falling apart? Are you just as enthusiastic about failure, more problems than you deserve and any number of disappointments, frustrations and adversities?
Passion is not an act. It is a way of believing. It is woven into your cellular structure just as much as your DNA. Passion - real passion for who you are, what you are selling, who you are becoming and what you believe in. It shouts to the world: "I am here to stay, I am here to make a difference, I will leave my mark in this world. It may take me my entire life, but I will not give up until my purpose and destiny are realized."
Are you in love with where you are, where you are going, who you are becoming and what you are selling? Or, are you living like more than 85% of the population with the attitude, "Same Stuff, Different Day?" If you have lost or are losing your passion for your career do whatever is necessary to get it back.
