Heart over Mind. Mind over heart.

Many times i come across situations where heart says something and the mind says something else. What to do. which one to trust.

I believe that following ones heart gives satisfaction. But we still follow mind and devoid ourselves of this pleasure. Funny i'snt it. But the real game is to follow ones mind and reach to a stage(could be a particular status in life, maturity or a specefic age) from where the mind says follow your heart.....
