Your heart will always be right.
According to me the brain thinks the way to keeps us happy. But the heart says to do things which makes others around us to be happy.
Most of the person who goes by the way of heart are nowadays considered as rough persons.
Brain is to think the way that heart tells us to do.
Those who understands this will become a matured one and can able to handle things during hard times.
So, always go by heart and do by heart.
Be cool and stay cool.
