Inquiet asks: “What do you do when both head and heart are telling you no, but everything else (a person you’ve always trusted) is saying yes?”
There are many questions we should ask of you in return, that you’ve left unanswered.
How much deliberation did you put into your judgment? Did you think things through, or just jump to conclusions? A trusted friend can talk you away from a hasty mistake.
Did the friend explain his reasons to you, or just expect you to surrender your independence to him? A real friend would respect you enough to want your understanding, not just your compliance.
Does your friend stand to benefit from the decision he wants you to make? Are his motives pure? Sometimes, though not always, we find our trust misplaced.
How much do you feel you stand to lose if you don’t act on your intentions? Just how well do you trust that friend, and how much does he feel you will be harmed by neglecting his advice?
Do you find that his judgment is noticeably better than your own, in general? Is it likely that he would see something that you wouldn’t?
These questions and more would need to be answered before we could really answer you. Without a lot more detail about your situation, we just don’t know enough to give your worthwhile advice. The question you pose is too broad to be answered, meaningfully. But it is good that you listen to both your head and your heart.
Ignore those who say “always listen to your heart”. The members of a lynch mob are listening to their hearts, and they have certainly been lead astray, remaining so mislead until somebody, as he listens to his head, decides to calm them down.
Ignore those who say “always listen to your head”. Logic, at best, gives one the implications of one’s assumptions – where is one to find those assumptions, if one dulls one’s perception of the experience of life, making a machine of oneself? Is one so sure that one’s logic will always be without error? Think of the doctors in the infamous Tuskegee Experiment, who in their devotion to perfect experimental design, watched syphilis patients who could have been cured slowly die. Their reason did not overcome their heartlessness; pure reason is no better a guide to life than pure passion.
It is when each serves as a check on the other, doubt being felt until head and heart are reconciled, that something akin to sound judgment and a decently pursued life will result. One won’t necessarily end up as either a klansman or commit crimes against humanity as a result of failing to respect passion or reason, but few take either failure to its logical extreme. Even so, there are a lot of less extreme ways of going crazy that one can see people devoting themselves to, every day, and less drastic ways in which they make themselves a menace to those near them, and themselves.
Best not to walk toward either of these extremes, but rather to follow a middle path, making a habit of seeking balance in one’s life.
