Never Plan Vacations in Groups
Do you remember your college years? You and your best friends for life (or at least until you guys graduate) plan on traveling to cities A, B, C, and D during semester break. At first, there are 50 guys in your friend circle who plan on going.

But as the days pass by, more and more of your friends come up with lame excuses not to go. Out of the 50 who go, only six of them say they’re down to go ten days before the trip. A week later, three of them had to cancel. That’s fine—you and the other two will have the time of your lives! But on the day of the trip, only one person ended up going. Sad times.
