Well yeah. At a certain point you've got to be really honest with yourself. Like 'Why am I doing this? What are my motivations?' Like if you get into it because you want to be famous? Then you've got a long row to hoe. But if you really feel like it's a labour of love and it's something you're actually legitimately good at then it's not that hard to keep plugging away.
I saw a drummer play once when I was a kid and I thought that's really cool. You know you're moving. You're using your arms and fingers. So I tried it and I loved it.
