I would say logic. Because to follow one's heart without logic would like asking for trouble. Want extreme example where logic and heart plays key roles?
Imagine the worst possible situation. Your heart isn't going to rejoice; it's going to be down and depressed. Your heart says let's end it all but your mind says otherwise because logically you don't know what's on the other side and it could be scary. Which would you choose?
Not convinced? Let's say you are really thirsty but have only 1 dollar. You see a vending machine but you are 25c short. Your heart says it wants water and now. Your logic says, let's see how I can come up with 25c instead of getting frustrated and beating the machine up, possibly lending me in jail. Which would you choose?
Not the type of example? Relationship? Let's say the heart wants what it wants... It'll end as soon as whatever stimulated the heart isn't there because logically there was nothing anchoring the two's values on the same place. Just mere emotions that can alter by the right stimuli.
Bottom line is that a decision made by mere spur of the moment with no logic is short lived and foolish. Logic based heart decisions on the other hand can be stable.

I follow my heart. maybe at that time the outcome is not good for me. but later I realize that it was something good in doing that. I follow my heart. my mind just puts negative thoughts. and even if at the time my mind seems right but what the heart tells is always somewhat beneficial
