Well I played the piano on and off as a kid (took lessons here and there, gave up, took lessons again, etc). Eventually I started composing/producing (on my computer) around 2005 or 2004. Which means I've been making music for around 6 years. I think most of my growth actually happened within this past year or two. I started making music with a friend which helped us show eachother our faults and how to improve on them. I feel like my music has just been getting exponentially better and I totally owe it all to practice and just keep going at it. Having people help you out and point out what you can improve on is also a GREAT help. I also find that going out there, watching tutorials, and just going on a basic quest for random music/production knowledge really helps.
