...is so far the best thing I have ever done...ever. I know people always say that's the best way to practice, and often I also tell people to do it, but I never really did it up until about a month ago. I'm still not nearly as good or clean as I would like to be, but my playing has improved tremendously since I started using a metronome. Definitely an awesome way to go
I started taking lessons a couple of years ago, and my teacher stressed the use of a metronome. I hardly ever practice without a metronome or basic drum track now, and my timing and phrasing have bother benefited from it.
