Interesting thought SKT. I found in my experience that with the proper perspective, being in the presences of those closest to you who don`t believe in you is motivation. The reason why it can be motivating (only with this a certain mindset) is because that is a tell tail sign that you are on the right path to tremendous success. "Study the masses and do the opposite." When you do what is contrary to the masses the first people to point it out are your loved ones. It is motivating to me knowing i have the vision to see what others don`t thus as I persist I will have what most don`t have.
