Would you plan practically or keep dreaming for better??

When my husband and I first got together we were broke as hell!! He quit his job to run his own company and I was just serving.. he had 2 kids and I had one.. being broke we fantasized a lot about the future and what we would do once we got the business going.. and we did good!!! First year of business we brought in $17,000 third year $160,000... don’t let the numbers fool you!! Since it’s still new we are still mostly broke, we get by! Because everything goes back into the company.. we had a baby and got married! Just this weekend bought our first house! It’s way better than I ever thought we would ever be at!! I’m 26 and he is 36.. I think practically and he thinks, well, fantasizes... going through what we need to do to the house he keeps saying “when we build OUR house, it will be this way and that way” and he wants to build like a fucking castle and everything made perfectly!!! We live in Pinellas county, FL by the way so idk where he is even planning on building this shit!! This county has barely any land at all.. and I’m thinking, why don’t we invest in the right things??? Like health, insurance, maybe even rental properties!! He even wants to buy a cyber truck!! Even “pre ordered” it for $100 and Says in 2 years he will be able to afford it??? And I’m like that better be after all of our kids have college taken care of, we have retirement and life insurance.. I’ve brought this up and he SWEARS we will have the money for everything in a year or two.. but I’m very simplistic.. I don’t need the best things.. it’s funny because we both come from poor families and both of our dads hit it big AFTER we left home.. and I mean poor, poor!!! Like I was the stereotypical Hispanic living in a 2 bedroom house with all my cousins and shit..he’s midwestern white so like his was he was in a mobile home growing up with 2 siblings!! I LOVE that he has these dreams for us.. but I really want him to get a reality check! We are doing better than our parents, for the time being!! Who tf knows what’s going to happen!! With him we went from having a home to homeless in a couple days!! I want to create a back up plan and invest in that but he wants to invest in these future dreams he has.. and we can’t do both!! Buying this house set us back a lot.. and unless we miraculously start making a million+ a year... we can’t back the dreams.. I try to be supportive and sensible.. but he is just fully believing everything will always be good now that we own a home and business!! It’s difficult
