Confidence. Passion. Confidence?

Some people say you gotta fake it until you make it. Some people say you gotta be passionate about what you do.

Can you fake confidence and make it into real confidence? What about passion? Can you ‘fake’ passion?

A common theme career advisors talk about is “find what you are passionate about”. I think thats bullshit. Passion is just as fakeable as confidence. You can be the most passionate person in the room about watering your plants in your office. Or the most passionate janitor in an old age home. You are either a generally passionate person, or not! Its that simple. Holistic passion. About everything and anything. Those are the most successful people. People who can get the same passion from selling newspapers door to door as they can from writing an artful piece of code.
And from passion comes confidence. When you are passionate about something (everything), you ooze it out. You are so engrossed in it that you can talk about it all the time. And you talk with authority. Awe. Amazement. With just a *little* more work, you become someone who can influence others to agree with your POV.
