Desire is what starts everything rolling in the Universe. It's what causes something to happen from nothing. However, don't confuse desire with expectation, or with need.
It is entirely possible to desire something without needing or requiring it.That small little, almost imperceptible difference, makes everything work. Desire, do not require. To desire propels. To require compels. Life will not be compelled, but it can be coaxed. What's your deepest desire for today?
