Heart vs. Head

When the two are in contention, which is it wiser to follow, one's head or one's heart? This question has plagued me for longer than I care to admit. My tendency, as an emotional, passionate, Scorpio, is to follow my heart. By "following your heart," I mean listening to gut feelings, chemistry, those things that just make you smile and feel like you're on drugs even when you're not. Giving in to these feelings can lead to a higher level of happiness than one can achieve with just the thinking mind. However, the heart is blind to the mundane realities of everyday life, which can result in extended lulls of unhappiness between the moments of bliss. If it does not at least balance out, you could end up with a net unhappiness, which makes me question whether those high-highs are worth the low lows. My brain sees this quite clearly, as an unwise life strategy, but my heart loves those highs so much that it's willing to make huge sacrifices.

Following my head has worked a lot better for me, in terms of net happiness, although it always seems like a fight against my natural tendencies. Hopefully following my rational left-brain will lead to situations where my heart is in agreement with my head. That would be the goal - a somewhat stable emotional state that is trending upward and sprinkled with the occasional upward spike. Experience tells me that it is wiser to follow my head, although I have a low level of confidence in that answer. The question itself is somewhat flawed in that it insinuates that the answer is binary and constant. Someone truly wise would know when to prioritize one's heart over one's head and vice versa. For those of us still seeking clarity, it would be useful to have a default.
