When you're a kid...you really have no idea of what you want. As you mature you begin to be more pragmatic, practical, too, and think out what is POSSIBLE for you to be.
For me? Definitely not the Poopsmith, but hey, in a younger year, I mighta clamored to be The Cheat.
I wanna be a writer...a teacher at a Christian school or something (I dunno...perhaps even a pastor or something)...or a philosopher. I'm positive I can be both teacher and philosopher at the same time; even CS Lewis was, and CS Lewis is paragon.
I would encourage my kids in what they want to be...but I would not let them grow up with these fanciful images that are not possible.
For instance, I have begun to look at life in three ways: 1. Sarcastic-cynicism (can you have one without the ohter?) (In my opinion, we outlive optimists 1:0)
2. God may do it (possible), but most likely won't (improbable)
3. God has done it (historical), but won't again (improbable)
FOR instance..."Hmm. YEAH! I think we COULD go down that path with the fresh, massive prints leading from man to animal...NOTHING will happen to us!" (Will say with sarcasm to accentuate cynicism)
FOR instance..."Yeah, Mom (big Holy Spirit Peace-pusher; really discourages my cynicism against people who encourage peace among the world), God may just make the world come to peace all of a sudden and we'll all believe in Jesus Christ...and did you hear in the news that hell froze over?"
FOR instance..."Yeah, sure, Mom...God DID resurrect Lazarus, but how many resurrections do you see on Earth nowadays? What? Zero? No way!"
So yeah. I'm a cynic to the end. My mom really hates it. I like it. I think it's more practical than anything else, and your survival rate is boosted to a high percentile by being wary of all things.
I don't want my kids to grow up thinking they can do anything (something Nacirema media loves to push through the boob tube). I want them to grow up with a sense of what they can and what they can't, of what is and is not.
They want to be an astronaut? Get to work on the maths and the physics sciences...screw focusing on English. Get to work on dem numbers!
Writer? Minimal numberal focus...more on the English. Want to be a botanist? Weeeeeeell...let's go to the yard, Brynn and tell me the name of every part of every plant I point out to you. Can't do it? Here's my high school bio textbook. Knock yourself out, Kiddo.
Work with the kids...don't discourage them, and don't encourage them in something they can't do, won't be allowed to do, or will detest (working on your knees as a scullery boy or dealing drugs between South American cartels).
