Greetings

My dear friend I really like your thoughts and you are right in your point of view because heart is very senstive and filled with emotions and the decision makes with hearts are sometime very sensitive because the element of emotion is much more as compared to the practical life because when we think from brain and make decision from the power of brain obviously they are more authentic and we can't repent much in our life.

As brain has wisdom power as compared to heart but as you mentioned you take both elements side by side in your life because these are vital organ of our life and had grear importance in life.

Good luck my dear friend
