I can sorta play trombone, but I'm pretty shit and really regretting not putting in more effort earlier, it was never really a big thing for me, partially because I didn't really see the versatility of the instrument. I began in year 7 (age 11ish) and I'm in year 12 (age 17) now, but I barely played the first two years and haven't done so this year. I suppose another reason I never committed to it as much as I should have done was because I only played trombone by default, and almost reluctantly carried on playing. I'm planning on starting a punk rock band now though, so I'm gonna save up for a cheap guitar and see if I can get a couple friends on board to do a musical project and this time take it seriously, because I've learned that playing an instrument can be very rewarding.
