Posterity is a bitch

The heroes of the 19th century Paris Salons, rich and successful in their day, are all forgotten today, while the impressionists they laughed at - those unskilled daubers who just threw paint at canvas and never added finishing touches to them - are regarded as the essential artists of their time. So worrying whether your art will be seen as worthy when you're gone is a complete waste of time.
You choose a set of values to guide your work and let posterity pick its own.
