People often do things while drunk that they regret when they sober up. Opening expensive wines is one of them. In order to solve this problem and, more academically speaking, to overcome the hot-cold empathy gap (proposed by George Loewenstein), I adopted traffic light system.
I place red sticky notes on the definitely expensive wines that I should NOT open while drunk. Yellow sticky notes go for the relatively expensive wines that I stop and, hopefully, think once more while drunk. Daily wines have no sticky notes. Thanks to this simple traffic light system, I regret less in the morning. 🙂
