Should I or Shouldn't I

So I've been going through a little situation and my cousin gave me some insight...So I thought I would share:

"Stop listening to your mind. You will not find the truth there. You may find the answer, but it will not be the truth unless it coincides with the answer in your heart. Your heart holds the wisdom. Your heart holds the future. Your mind knows nothing but the past. Therefore, it makes decisions based on that."
