My advise for what it is worth is
1. Read Rudyard Kipling's poem "If"
2. Don't define your career path in advance, let the wind blow you where it will, but embrace every change
3. Practice, practice, practice till your fingers and ears bleed
4. Don't dismiss music based on genre learn from the differences it offers
5. Find out your strengths and weakness before anyone else does and work with them
6. You are not unlucky, everyone else has to deal with a*seholes too!
I started off as a musician, became an engineer because I loved being in the studio listening to my songs develop, became an engineer through soaking everything up like a sponge, mixed the two to become a producer, then travelled the world doing sound for a living. Couldn't have dreamed that coming from a backwater in Australia.
My band mate started off as a musician started the whole genre of sound/look alike bands but made his money doing songs for kids programs
My brother started off as a classical musician, now runs his own guitar school and has a worldwide distribution for his guitar and ukulele books and is well known as a blues guitarist in Australia.
Another brother started off as a drummer, found a non secular passion, gave up rock music because of it but then ended up playing the organ in his church.
oh and finally
7. Don't believe people who say you are better than you yourself know you are, they will suck you dry!
