I do, because figuring out what is going to be big 30 years from now is hard (arguably impossible to do deterministically), but knowing what is big now is easy, and wishing you could go back and capitalize on that is natural.
A lot of people also spend scads of time contemplating how they would spend the money if they won the lottery and it's generally a waste of time. They probably aren't going to win the lottery and it usually isn't used as a stepping stone to making real life decisions about, say, what kind of career they want to pursue or how they wish to spend their retirement.
I used to do that sort of thing and then began going "If I value x, why sit around telling myself I can't possibly have that or some piece of that without winning the lottery? Why not do what I can to actually work towards that to some degree, in some fashion?"
So you may get it. That's fine. I don't and that's not commentary on anyone but me and how my mind works.
