That following your heart is impractical. It's true that one's feelings, especially when untrained or inexperienced, can be wrong. But the solution isn't to disavow feeling. Feelings are at least as much of the substance of you as your thoughts are, and perhaps more representative of your base self given we lack direct control over our feelings.

The solution IMO is to train your heart to be practical by following your heart over and over and over again until your head and heart have little to disagree about.
