I suggest reconnecting (or spending more time) with nature, animals, children...things and beings that make you more heart-centered.
I also recommend reading about spirituality. Spirituality is the key to living from your heart, rather than your mind.
When people get caught up in the "real world" (i.e. making money, success, and even education), they lose touch with the simple pleasures and joys of life - the true meaning of life. By exposing yourself to these things again, you will reopen your heart and have more right/left brain balance in your life. It will take time, but be consistent and it will come back to you
