Where to begin?
I've never used starsan... I used to use clorox, but kept staining stuff. Just went to Oxy-clean free. I didn't use to rinse, either, but am starting to (wonder how many off flavors the white powdery residue has contributed or what health problems I've created by drinking it???). Started doing a quick rinse when I added TSP to the Oxy-clean when I made the generic PBW substitute found here on HBT.
I've never cleaned/changed my beer lines (see also #1)
I often don’t want 5 gallons of something I have a taste for when I’m ordering supplies. Sure, I like Belgian beer, just not a constant steady diet of it until the keg's gone. I need to brew more so I have more choices. I have a 3 tap kegerator, but usually only one on tap.
I sometimes drink Miller Lite when I’m low on HB, whatever’s popular at the bar if they don't have GOOD craft-beer (hell, I even had a PBR before a Cubs game at the bar across the street from the stadium because that's ALL they had), wine, or nothing.
I have too much glassware… not enough beer. Guess I need to brew more.
Was married to the wrong woman for 20 years… one who didn’t support my habit/hobby. Though I brew outside, making a starter in the kitchen was rebuked with taunts of, “What’s that cat puke smell???” Remarried and am very thankful for her support!
Not enough uses for all my spent grain… I use spent grain flour for bread and pizza crusts, grain used for dog biscuits… and still I dump a ton in the yard :-(
I've never entered a competition (in 31 years brewing) :-(
Oh, and on those lines, I **JUST (as of January, 2015)** started all-grain brewing. I should have started sooner - there isn't any voodoo magic involved, it doesn't require significantly more time (like I thought), and not a ton more equipment required. This is my greatest lament/confession. Newbies - just do it

This is all anonymous, right? ;-)
