You Overvalue What You Already Have

The mug you own feels worth more than the identical mug on the shelf. This is the endowment effect: we assign higher value to things simply because they're ours. It affects everything from salary negotiations to relationship decisions — we cling to what we have, not because it's objectively better, but because losing it feels like a loss. Recognizing this bias can help you make cleaner trades, let go of outdated commitments, and evaluate your options more honestly.
