Possession of original art brings you this unique filing pleasure in the sense of connection with the artist, especially if you've met them. There's something very special about having a tiny particle of someone else's creative mind in your home and it's inspiring.
For many, buying art is major lifestyle choice. some, don't have any painting, because you never felt like inspired to much to buy it. Many become passionate collectors for life starting very simply with a single piece of art bought on impulse. Doesn't matter if you know a lot about art, most important whether you like it or not. I don't pay attention to my art collection every single day but there's not a week goes by that I don't suddenly notice one of the pieces I own and get a sudden surge of visual pleasure. Besides, let's face it, humans mind is very competitive. We often buy art to have something on your wall that our neighbor doesn't have yet. It is truly not the least reason why people buy original art.
