Artist

I overheard an english tour guide saying this interesting comments to the visitors in the Vatican Museum yesterday. She said "If you are not an artist, you can be an art teacher. If you can't teach, you can be a critic." This is a point with a strong sense of humour. 

I'd like to add a sentence though. " If you don't like criticising, you can be an admirer. " Surely you will be more popular in that way.
