Be real. If you seem fake or insincere, no one will be inspired. They would never be impressed with you if you are trying to be someone. They have to think that you believe what you're saying and you have your own concept in life which you believe in living it. If you don't believe, if you're just peddling snake oil as it were, then why should they believe you? The best way to be real, and show that this matters to you to is to make it actually matter to you. Be enthusiastic and throw yourself into what you do. After all its your life.
