Dream on, dream on
Surely most youth (including our past selves), truly get obsessed with daydreaming (and I don't mean s#+) — just the castles in the air with no brick and no basis (foundation?), etc.
Can this actually be helpful? No one to play a board game with when bored? “Dream a little dream of” anyone, anything. Children unattended often do play make-belief — is that a natural instinct or latent potential for creative expression? Can you think aloud and solve a problem or plan a course of action? (well, talking to Google Maps or asking Siri/Alexa doesn't count!).
You could probably "pray" or "wish" for the habit of daydreaming to go away, but if it’s there, it is probably serving some purpose or some void.
Some of the top sales guys practice their pitch all alone in front of a mirror or job-applicants prepare for interviews by simply visualizing and imagining an interview taking place beforehand.
BTW: daydreaming is not the same as ambition. For example, you could be “dreaming in the USA” or you could actually have a plan about getting there and what to do once you are over there. (That album by Sting itself has over a dozen ideas to write home about —(get the Deluxe Edition)).
Daydreaming’s Dark Side: The Disorder That Dominates Some People’s Daily Lives
Maladaptive daydreaming affects about 2.5% of people. Despite what we’re often taught to believe, daydreaming can be immensely useful.
