If you want to develop yourself as a person and as a musician go for the instrument that has your voice.
In the sixties I played slidetrombone and sometimes guitar and banjo in dixieland groups without really knowing what I was doing but I earned a lot of money with it. Round '68 I became a student of law and because dixieland was out of favour I changed to bassguitar to earn my money. All my life I had a piano in my house and in my thirties I decided to study classical piano to develop MYSELF. I did need all that time to take musicianship seriously. In 2008 (I was 60 then) I bought on holiday in India for fun a new Empire Brass pockettrumpet for 20 US dollar. That started a whole new perspective. I found out that for trumpetplaying I had to change my whole personality. First I had to learn to breath in a complete different manner and that cooled down my somehow what active personality. Second, according to Lee Morgan: trumpets are for extroverts. The trumpet is a very honest instrument, you can't fool it. So the trumpet forces me to be a more honest person (emotionally). Al Hirt is a FABULOUS trumpetplayer but if he plays f.e. a ballad I hear nothing, particularly not himself. Miles Davis can play two notes that you and I can easily play but with Miles they have a lot more meaning. That's because of what he shows of himself. Bix could do that and of course Satchmo. Trumpetplaying is for me very addictive, I need it to force myself in the (for me) right direction in the development of what kind of person I want to be.
So it's not about succes but still about worth.
