"There is not set path, just follow your heart"
{Anon}
When your heart is fragile and weak, don't follow it. When you have zero motivation or have feel like there isn't a motive to be on going, don't follow that thought. Only be ready to "follow your heart" when you know that is the safest and greatest choice of your life. It'll be foolish of one to follow a heart that is useless.
