Hi rats_and_cats,
I'm an artist.
Being an artist is definitely not my full time job ...
Sure, I make sales once in a while,
but it's more like
I need a day job in order to afford being an artist.
And I say this as one who has had my artwork exhibited in art galleries, museums, and solo shows.
In fact, my photos and paintings are currently on display at a government building ...
and I won't make a penny from this current display ... in fact, I'll lose money
if you consider things like time packing and unpacking the car, travel time, gas money ...
I also have an online store, and yes, I make sales.
That said ... Once again, I'm thankful for my day job.
This isn't meant to be discouraging, just to be real.
And the reality is, I love being an artist. 
In your case, some questions to think about, if you want to sell art, or otherwise advance towards
some common artistic goals:
1) How marketable is your art?
2) How do you market your art?
3) Where can people see your art?
4) How interested are you in other people's art?
5) Have you entered your art in local exhibits at art galleries or museums? (If not, why not?)
6) Do you sell your art at craft fairs, art shows, consignment shops, gift shops, online?
In answer to your question ...
being an artist can be quite lonely.
Many people won't care.
Some will laugh at you.
Some will make rude remarks.
Some will get jealous.
(And yes, every once in awhile,
you will inspire someone, and
someone will pay you the nicest compliment ever!)
So you really have to want to be an artist ... writer ... photographer ... fill in the blank _____ kind of creative.
Wishing you all the best of success in the New Year.
(And may I please see some of your artwork?)
