Woah woah woah you can't challenge people to grow their moustaches and then flake out and say "maybe I'll trim." If you want other people to do it you gotta be damn sure you're doing it yourself. A year is a long time but I haven't trimmed my stache since August and honestly the first 2 months were the hardest. A lot of my stache has reached terminal legnth but it has been smooth sailing since the initial itch to trim.
