Never downplay what you are passionate about, especially around others. Making that mistake is easy because we are often not where we plan to be as it pertains to our goals and we want to be “realistic” or too polite.
Making “less” out of what you are trying to accomplish is extremely counter productive. Not only does it put that thought in your head – it puts it in the head of the person checking in on you. If you unsure about what you are doing or lack confidence, they will feel, see and hear it tenfold.
The positivity, passion and belief you create within yourself, what you are doing and what you are about is far more important and powerful than you may realize.
