I started out in the hobby over a decade ago with a 20 gallon, then eventually I upgraded to a 55, then I took down the 55 and didn't have fish for almost a year, then I set up an old .5 gallon bowl and got a betta, which sparked my interest in fish again, so then I got my 220 last July, then I upgraded the betta tank to a 2 gallon because I decided that it was cruel to put a fish in an unfiltered, un-airated tank, and my next tank will be a 5.5 gallon. If I ever get a tank that is larger than my 220, it will be years from now when I have my own place and the money for maintenance.
