The first paragraph of the Shulchan Arukh (Code of Jewish Law) states that on waking one should contemplate that God, Who fills the entire universe with His glory, is standing before him, and he should rise energetically to serve Him.
One who can indeed visualize this picture with its full tangible import need not be told to do anything; as a
logical consequence, he will leap out of bed and rush to his Creator's service.
The problem arises when his mental screen is blank, when he opens his eyes in the morning and, at best, knows that such a passage appears in the Shulchan Arukh.
Such a person needs to be told, and must tell himself, what he should be feeling.
And on the strength of his knowing what he is supposed to feel, he can get up and function properly.
