If you’re afraid you’ll lose your chance by letting the opportunity pass, you might act quickly and then later regret your momentary lack of fiscal discipline. However, your sense of urgency is an illusion and can prompt you to overreact. You can avoid buyer’s remorse if you simply take extra time to weigh your options prior to opening your wallet.
