uhhh, bill, i was looking around in google street view like you said you sometimes did to write, and i accidentally wrote half a song (whoops). the funny part about this is that i have never actually written a song before (or at least nothing longer than a handful of bars). i also don't have the skills or tools needed to MAKE the song (or any music for that matter). so i guess the logical thing to do would be to spend next few years working to gain the musical skills needed to make this song and many others real?
sure, that would be fine. although there is no exact goal-post for when you are 'good enough to make a song'. you could practice your whole life and not really be good enough, or, you might be already good enough now. just go ahead and write down the song somehow (make a recording and try to sing it and/or describe everything you know about it) and file it away and then when you feel brave enough you can do it
