Your passion, your new purpose will change you. Great ideas do that. But eventually, you will encounter friends, family or even random people who don't agree with your great idea. Believe me, it's inevitable. But that shouldn't discourage you. They are not mad at your great idea. They are disgruntled with the fact that you made a conscious decisions to break from the status quo. They are seated in discontent toward you, because when you change it forces them to change. Hell, its human nature. I am sure if the shoe was on the other foot, you would do the same.
