Rebalancing out of TQQQ after a run felt completely backwards

Been running roughly 60% VOO and 40% TQQQ in one account and after a strong stretch TQQQ had drifted to almost 48% without me really noticing. My plan was always to rebalance once it got more than 5% away from target but actually selling the thing that's been carrying the portfolio felt way harder than writing that rule down. I ended up moving around $2,700 back into VOO, had moon open while doing it and definitely hesitated before submitting the second order. Nothing complicated about the rebalance mathematically, I just underestimated how weird it feels cutting the position that's currently making you the most money.
