Is it worth the trouble to build vintage sets?

I love to collect sets, but my budget won't allow for me to complete sets from Pre-War (for the most part), so I am restricting it to 1948-present. I don't exactly collect like the rest of you. I can't focus on one set at a time. I get annoyed with it. Literally, I can be all in on a set one day, and a day later I don't even want to look at it. So, I set up a plan about 3 years ago. I listed all of the sets I wanted to complete, and decided to do it on a 10 year plan. I would make sure that each year I am at the 10% more mark each year. This year, my goal is to be at 30% or higher for each set by my birthday in August. I am only a few cards away from that goal, so I am right on schedule. I also assign a points value to each set, so I make sure that I am also picking up a fair amount of star cards for each set as well, so I am not stuck at the end with all of the toughies.
Doing it this way seems illogical. But, it keeps me interested and always relaxed and enjoying it. I have also finished quite a few sets in the last three years already, so those no longer are in play. I am not a Mint freak. I just like good looking cards. For the 60's, I am happy with Excellentish cards. For the early 50's cards, vg/vg-ex works just fine. I am working one 1940's set, and one 1930's set. Vg is just fine for those.
