I saw Damien Rice in Dublin when I was 13, and that inspired me to want to pursue being a songwriter... I practised relentlessly and started recording my own EPs. At 16, I moved to London and played any gigs I could, selling CDs from my rucksack to fund recording the next, and it snowballed from there.
Try to find someone with a sense of humor. That's an important thing to have because when you get into an argument, one of the best ways to diffuse it is to be funny. You don't want to hide away from a point, because some points are serious, but you'd rather have a discussion that was a discussion, rather than an argument.
But once you've made a song and you put it out there, you don't own it anymore. The public own it. It's their song. It might be their song that they wake up to, or their song they have a shower to, or their song that they drive home to or their song they cry to, scream to, have babies to, have weddings to - like, it isn't your song anymore.
