Well the alternative is doing a valley of ironing so world-building wins hands down for me
On a serious note, creating a new world from scratch doesn't happen overnight. Just like everything else revolving around writing. I go through spurts where I'll map out my world, or sketch landscapes or townships or people to inspire me/remind me of the world I've created thus far. And research when I get an idea, like basing different nationalities on astrological signs and brainstorming a sort of culture based on those and their environment. Etc etc etc.
My recommendation would be not to fuss about those small details until you have to. Let the story and the characters take you where they will, and then go through the whole thing once it's completed. Don't fill out all those hundred questions about it because someone said you should. Pick and take which ones are relevant to your world only and keep them handy in your notes.
I mean my astrology temperate nations/peoples I've created? >POOF< Gone, cut out. I'm down from 12 different nations to only two. The big kingdom with all the duplicate marble bungalows I used to obsess over drawing? Yeah that's finito now, too, and they've gone subterranean, which changes E.V.E.R.Y.T.H.I.NG.
The thing with world-building is that it can be daunting because it's massive just how much you need to take into consideration. But the pay-off is that you can do just about anything you want (within reason of the genre).
