With more experience maintenance becomes easier and less time consuming. I know I spend little time maintaining my tanks once they are setup and it doesn't really matter what size they are. However if I think back and imagine if I started this hobby with the tank size I have now I would probably not be in the hobby anymore, nor would I still be married
I know I hear the phase "start with as big of a tank as you can" quite often but it's mostly in LFSs and it seems IMO to suggest something more along the lines "spend as much money here as you can".
