Don't dilute your motivation. You've probably heard that sharing your dreams with others can dilute their power due to negative comments or disbelief. While the people closest to you want what's best for you. They often can appreciate your vision. They think that they're doing you a favor protecting you from disappointment by pointing out all the potential problems with your dreams. This also applies to your motivation.
Have you ever been fired up and feeling good only to be cautioned by a friend or family member? Has anyone ever told you to get real when you show excitement over a new possibility? The truth is you cannot rely on others to support your motivation. No matter how much these people may care about you. They usually dismiss what they don't understand. We often feel compelled to share our new goals with others when we aren't feeling confident about them.
If you must seek advice and encouragement along your path, seek it only from those who have accomplished what you are trying to accomplish.
