Uncertainty is uncomfortable, and committing to something resolves the discomfort even when it does not resolve the question. That is why premature commitment is so common: it trades a real unknown for a false certainty. The relief is immediate and the cost arrives later.

When you feel the pull to just decide something, check whether the pull is coming from the situation or from the feeling. If it is the feeling, find another way to sit with it. Tolerating not knowing is a skill, and it saves you from a lot of bad commitments.
