Two ways of doing a job

I don't know why this fictional scenario came into my mind this morning, nor do I know why I decided I should immediately recount it to you here. But I try to trust that if I make the vessel here then it will fill with light all by itself, at which point I can cry out "Shazam!" and take all the credit for everything.

A person goes to a Doctor and says "I got more than nine hours sleep last night and I'm still incredibly tired!"

The Doctor says "Hmm." And begins a very thorough examination. The Doctor asks the person many questions, like "Do you often have insomnia?", "Do you snore?", "What do you eat before you sleep?" and so on. The doctor conducts several inconclusive tests and then, ultimately, recommends that the person go to see a sleep specialist. The Doctor gives the patient the name of the best sleep specialist in town and finishes the appointment.

Another person goes to a Doctor and says "I got more than nine hours sleep last night and I'm still incredibly tired!"

And the Doctor asks "How much sleep did you get the night before?"

The person replies "Four hours."

The Doctor says "Sleep shortage is cumulative. Get another good nights sleep and you'll feel much better." 

The moral of the story?

Sometimes you have to put the light into the vessel yourself.
