Let's think about it in 3 steps... The first step is to TRAIN YOUR EYES: Visit lots of museums where you can see the best quality art works and see them as example of 'good art'; LEARN ABOUT ART: Read art books, visit art courses, see art auctions. Try to understand the philosophy behind artists' messages; And lastly, FORM YOUR OPINION: About art that you like and connect with the most, form your taste in art.
