“Whoever it is that’s trying to siphon off your time and energies for their own purpose, the only solution is to put up fences. And not at the moment the quest is made—you need to put up your fences well in advance, clearly demarcating what’s off limits so you can head off time wasters and boundary pushers at the pass. Remember, forcing these people to solve their own problems is equally beneficial for you and for them.”
