To the OP's question, I remember as a kid being filled with joy, knowing that my day was spent in service that pleases YHWH (just like Little Caleb in that cartoon feels happy knowing He made God Happy, not Sad....). However, in looking back at my own experience, it's pretty clear that any sense of satisfaction and joy was being created by ME, an internal emotion of MY own creation.
That's the problem with externalizing one's happiness to others, including imaginary beings: anything act that is good is robbed from the individual, who cannot say "I did that of my OWN accord", but must say "Was that good enough?". It robs individuals of their power and their responsibility to do things simply for their own sake, not out of following orders to save one's own skin.

I'm reading a FASCINATING book written in 1940 by RB Orions, called "The Origins of European Thought: About the Body, the Mind, the Soul, the World, Time, and Fate". It's a deep scholarly work (600 pgs, with plenty of footnotes) that examines beliefs of ancient men, be it Greeks, Romans, Babylonian, Assyrians, Hebrews, etc.
(Disclaimer: JW's needn't bother, as such secular study and independent thought/ applying logic is heavily frowned upon by the GB. You are FORBIDDEN to learn this kind of stuff, per your last DC, as it's defined as "testing God" to do so).
So, it turns out that the authors of the Bible relied quite heavily on the worldly knowledge of the other cultures' in their vicinity, be it for their understanding of astronomy, anatomy, origins, or common folk-lore/myths. In fact, the cosmology depicted in the Pentateuch was/is based on Egyptian and Babylonian beliefs of the period (1,000 BC) which are still seen on tablets, even to this day. Interesting, as you'd expect a book that supposedly was "inspired by God" would NOT contain errors that are obvious to any modern kindergartener today? The anatomical ignorance is simply inexcusable, given that the book claims to be inspired by the One who made men.
One element Onians writes about are words people toss about, without thinking of their origins; eg "inspired", or "Holy Spirit".
In a pre-literate World, ancients believed thoughts and ideas were formed in the lungs, not the brain (there's no mention of the brain ANYWHERE in the Bible; also why Egyptians didn't bother saving it with the mummy: they didn't know what it did, and hence discarded it). The word 'spire' is still with us today in reference to the lungs, eg 'respiration' (breathing in and out to let oxygen in, CO2 out), 'respirometer' (device used to measure lung function), etc.
So ancients believed that ideas were transmitted to others by the act of exhalation while talking. The theory worked for them, and it made some sense: you need to exhale as you talk (try to talk as you inhale: you cannot do it, as the vocal cords don't work that way). So they believed ideas left the lungs, travelled thru space, and were received into the lungs of listeners. This theory had to be modified once writing came on the scene much later, but it worked to explain communication.
Greeks and Hebrews also believed that GOD(S) could directly and silently inject their ideas into the lungs of chosen individuals, via "inspiration"; YHWH does the same, using the medium of his "Holy SPIRit" (there's that word again, spire), the vaporous matter that contains ideas.
It should be apparent saying "inspired by Holy Spirit" is circular logic, at it's best.
PS God also breathed spirit (Hebrew word "ruah") into Adam after he fashioned his out of earth, giving him life/soul (Hebrew word is nephesh).
