I used to think that some beers were too far out there to try, now I am more than willing to try something at least once.
I used to think I'd get to a certain level of homebrewing and be satisfied with my equipment and results.
I used to think that talking to complete strangers on the internet was something I didn't want to get involved in, now I look forward to answering questions on the forum, shooting the shix in the chat-room, and actually meeting some people from the forum.
I used to drink a 6 pack of beer in a month, now I can go through double the amount in a week sometimes.
