All people can be an artist in this era, yes, so I can be.
To me, art is a self identity challenging process which is responsible to one's life. When you are brave enough to step out and try to communicate (not already get an answer of) "who you are" as an unique entity, congratulations, you are already an artist!
Of course, no one will actually interest who you are. If you would like to get someone's attention in "who you are", well, this can be a great side business of selling yourself as the product!
