How can I make this career change - Marketing/Admin to Fine Arts?

I've been through 4 years of university and gained a bachelors degree in marketing and management communication after 2 (almost 3) years working in the industry, I've found that I rather passionately dislike marketing!

So for the last couple of years I've really just been bumming around working in odd admin jobs that are seriously unchallenging and uninspiring. To make up for it I've taken up art again and spend a lot of my spare time painting and sketching and am spending more time learning about the arts... I really enjoy it.

So what I've been thinking for a while is how I could make a career change into the art industry. I really like the idea of working in a gallery or something along those lines where I could be more exposed to other artists and events in the art world.

Is there a way I can do this? Without having to go back to school or beg for work?! I'm earning good money in what I'm doing, I'm also a bit worried about a major pay cut and how that would affect my current lifestyle. But then again I guess money isn't everything?!

Any feedback, tips or experiences you might have would be really great to hear!

Thanks for your help :)
