What Is the Key to Making a Career Out of Your Art?

I never seriously considered my art to be a career. I always considered a regular job the smart option. And then i used all my spare time for art. The big sacrifice, the huge sacrifice, there was a social life. 90 % of the time that i should have been out going to pubs, meeting people, relaxing, i didn't. But now, years later, i i'm now in a position where my actual job is doing that. That's actually my comforts on it doesn't feel like work. It could be gone next year, could disappear. Next year a flit o, a switch could flick and a social media ap just says, pad casts are no more
