This thread has gone on way too long.
It is very simple really. If you want to follow the path of composing
(as I have done professionally since 1980!) if you have to ask yourself whether to bother or not then it is simply not for you. That fact alone means you are not decided.
It is a bit like should I marry this guy or girl. If you even have to ask that then obviously you are not ready for such a thing. Same thing with composing. For me a light bulb went on when I knew that is what I had to do. I have never stopped since and nothing will get in my way of continuing doing it either.
