I play guitar, sing, perform and compose music.
A great day at work is writing for a good four to five hours - this could be lyrics or music, by myself or as a cowriter. Songwriting is a huge priority for me. Of course what I do calls for a lot of practice time on guitar and voice. I spend a lot of time learning other people's songs and rearranging them and that gives me more ideas for my own songs. After that, there's always administrative stuff to do like sending out booking requests, promoting putting shows together.
The biggest skills to learn are networking and collaboration. Both of those things take a lot of practice. You have to learn how to be fun to be around but also tough when you need to be so people don't take advantage of you. Working with other artists is huge because doing shows and releasing music requires other art forms. The best product - be it a song, an album or merchandise - goes through a lot of changes before you call it "finished" so it's also important to be open to criticism.
Here's the first step for high school students
It's not enough to just sing or just play an instrument. Do your best to get good at both!
"Too many people want to be musicians. You might be among the most talented at your school but that doesn't mean you'll be talented compared to the rest of the world. It's better to just go to school for something that will actually make you money."
