I always say that I can help someone who can already compose, but if they can't, I can't help them. I can advise on technical issues, of course, like how low the piccolo can go, but otherwise what's important is not wisdom but enthusiasm.
I hike every day with my dog, after the kids are off to school. I tend to get wrapped up in all the things that need to be done during the day, so I really am strict about setting that time aside for myself and not scheduling anything before eleven, so I can get my hike in.
