I thought this story might be especially effective, being Easter and all. Forgive me if it offends you, but I think there is a great lesson to be learned.
A friend was sharing a story about survival training he had done as a pilot before going off to battle. He and others were literally dropped off in the middle of nowhere and were to spend the week surviving until they could be rescued.
The week prior to being dropped off, each one was given a bunny. They were to name and care for their bunny for several days, treating it as a child or beloved pet. They brought the bunny with them during their week of surviving in the wilderness. (Some of you see where this is going...)
Most were able to hold off for days with no food or water, until they broke down in a moment of weakness and had the rabbit for lunch. Although, by that point, it was too late. They were already in a state of exhaustion and not able to think clearly.
The lesson of the bunny? Eat the bunny early. Keep your strength up and you wits about you in all areas of your life, instead of letting yourself become weak, depleted and unable to think through decisions, resulting in acting out of desperation and panic.
