Two things: 1) you have to develop a skin if you're going to put something in front of an audience. Whether dance, music or painting, there are going to be people who love what you do and people who'll hate it. And the skill is to hear the germ behind the critique.

RE: cause i think the best way to build an artist is to give them a pat on the bach ,the rest they will learn in time

I disagree. A pat on the back is one thing, but sometimes a kick in the ass is good too. One of the reasons why visual art went from something of a craft with skill and training to the stereotypical foppish guy in a beret throwing random blotches of color on a board and calling it "Art" is because noone said "this is crap" when it first showed up. If we'd had the guts to take the works of Paul Klee and publicly burn them when they first showed up, then none of the rest of this dilletante nonsense would be plaguing us today.

A violin teacher will not accept sloppy fingering, nor will he accept off-tune notes or bad time keeping. If you're going to play the violin, damn it, you'd better hit every note on key. However, that being said, there's a difference between saying "I'm sorry, please stop there, we need to work on the way you hold that thing before anything else" and bringing a ruler down on the student's fingers, screaming "get that horrible yowling thing out of here!"

Quote ...i think its a shame that people spend countless hours learning to paint like the masters...and they dont get 1/2 the credit as some guy thats obviously only been at it a week,..and cons people into thinking his work is something from the spirit world.

Should you really be calling it a "con" if by your own admission, you don't understand it?

The difference between a masterpiece and a finely crafted pastiche is TINY; but it's that difference that makes it so special.
Henri Matisse can make a simple A4 line drawing of a face in 5 minutes, that'll capture more of a person's character than a life-size heavily worked oil.
Most realistic paintings have little more artistic value than a cathedral make from matchsticks; whereas say Albers, can make 4 coloured squares evoke a summer's day (by carefully/intelligently choosing the dimenstions, tones, composition and finish.)

Think of a quality abstract picture as a precious stone, rather than a poor attempt at pornography.

Abstract Art: A product of the untalented, sold by the unprincipled to the utterly bewildered. - Al Capp

They're more like craftsmen; and are usually rewarded similarly.

We all know that art is not truth. Art is a lie that makes us realize the truth. - Pablo Picasso

Abstract Art's often a kind of metaphor, stripping things down to their most basic forms; focusing more on balance, harmony and tension than literal representation or narrative.
If done well, it can be really quite visceral and haunting.
My advice: Read the title, find out what the artist's intention was, and most importantly see how it makes you feel when viewing it and does it stay with you?
