I've been working as a flash animator for 15 years.
I did do a great year in animation school which gave me the best start. Mostly because of the people you meet. I'm still friends with them all today and we are all in varying industries now.
Though some of the responses you've garnered resonate with me, I find them a bit negative.
Maybe the truth hurts a bit. I can't say I disagree with what's being said, but everybody will have a different experience that will shape them over years of doing work like this... I've met quite a few people that have become a bit "hardened" over the years or have even thrown up their hands and left it all for something stable.
Though I don't think I've had an extremely difficult time trying to make a living for myself, there are many ups and downs to it that can't be ignored.
It's been a challenge to make desirable income on a regular basis, unless you are going with a studio. But depending on the studio, your experience in animation could totally suck... it's a personal thing that is really derived from what you make of it and what you learn from experience.
If you are a positive, creative person, with a great eye for detail and an abundance of patience, this could be your calling. If you are a person always in a hurry, doesn't want to keep learning, doesn't like having his work critiqued or wants the glory of calling something done when he wants, maybe you could try being a producer. (haha though I'm half kidding)
Anyways, I don't want to discourage anybody. Though the graphic design studios were usually the places to learn the most from others doing what I do, I am much happier choosing my work as a freelancer. The freedom at the moment is worth it to me. Some folks like being in an office 12 hours a day, working the free OT... I've decided I want something different and have put my efforts to something more personally fulfilling.
But that's another story that comes along with practice, and the willingness to keep going. I'd say you almost need to forget what some are saying in here and try to have what I call an "ignorance to the fact that the odds are against you".
I got into this because I thought animation was all funny hats, funny voices, funny faces in mirrors. It's a lifestyle and one that often won't include making cash. It's the other side of it that I think has the true lovers of animation hooked.
Tips to succeed?>
Learn to make good work first, and the good stuff will come with time. Have that spirit of effort to improve, which it sounds like you already have. And DO be willing to poke around the Frederator network... It's not a place to be embarrassed about work... getting used to opinions you don't like, is paramount. You also live in the age of communication and there are people in there with FREE info to save you time! Again, going to school (even a summer class) will be invaluable if you are serious.

Don't be discouraged.
Do it on the side first.
Get opinions and be humble always.
And then, do it until it's not fun anymore.
I can't think of any better advice to offer, personally.
There are people who make something special and memorable in animation. Something that sticks. Keep inspired/
They have all started at the same spot you are, so have some comfort in that fact and just keep doing it, no matter what.
If you want it enough... you can get where you want.
