Happy for you bro!
I've also really slacked on my editing since I started my YouTube channel about a year ago. I feel that it's probably one of the reasons for the lack of growth on my channel.
I finally decided to get Premiere Pro last month and have been toying around with it. I'm getting better but I haven't been using it lately because every time I import a video, it ruins the synchronization of my audio and I have to spend all day trying to line things up.
So I've gone back to just using iMovie for now, which obviously doesn't have nearly as many tools as Premiere Pro does.
