Playin my guitar is one of the most relaxing things I have found to occupy my time. I can relate with what you guys are saying about losing ur musical abilities around other people. That's why I usually play by myself. I can make up songs on the fly, but I can't play with a band haha. Self satisfaction is what it's all about. Relaxing and escaping into the realm of music. Anybody can make music, in my opinion. Just gotta learn how to let your mind flow freely after lots of practice with your instrument of choice. Simple as that, although it takes years for most, some are musical geniuses right off the bat. Just goes to show another way in which people's brains differ greatly. 5 year old playin' Mozart on the piano is always a trip to watch haha... You people have probably seen these little musical geniuses as well. I find it quite interesting, indeed.
Peace
