How do you choose........

So i had an interesting conversation today with my cousin, Ms. Kayla Thompson, and my question to the rest of the world is: How do you know to choose between your heart and your mind? Which should you follow and which do you follow more? Think about the experiences you've had in your life, and which one did you follow during those times. Were you right for choosing the one that you did or do you regret it and made a huge mistake..i need your feedback women please let me know......Love ya
