Reddit mentions of de Kooning: An American Master

Learning art is a marathon, so here are some suggestions to help with motivation for the long haul:

• Read artist’s biographies. Get in another artist’s head and find out how they do/did it. I like de Kooning: An American Master.
  
  
  
• Visit art museums. Take a notebook or sketchbook, and when you see artwork you really like, write down the artist’s name and find out more about them and their style. Most museum bookstores carry books on the artists in their museum and inexpensive posters of their artwork. (Hanging posters in your drawing space is inspirational too.)
  
  
  
• Attend local gallery openings. Being around other artists and people who like art is exciting and motivating.
  
  
  
• Purge those demons. Keep a journal that is purely stream of consciousness writing and unstructured. Fill a notebook then shred or burn it. (See The Artist’s Way below.)
  
  
  More good reads that will help you learn why you want to draw and why you are having trouble being motivated:
  
  
  
• The Path by Laurie Beth Jones. “Using the simple process Laurie outlines in this book, you will be instructed in how to actually write your Personal Mission Statement for Life.”
  
  
  
• The Artist’s Way by Julia Cameron. “…the seminal book on the subject of creativity.”
  
  
  
• The War of Art by Steven Pressfield. “The War of Art identifies the enemy that every one of us must face, outlines a battle plan to conquer this internal foe, then pinpoints just how to achieve the greatest success.”
  
  
  Bonus Points:
  
  
  
• Write an art statement, vision statement, mission statement and set short-term and long-term goals.

This is a fantastic book about de Kooning but it also goes into a lot of art history and shows why these guys were able to change the face of art.

It is not just a great biography, it's one of the best books I've ever read.
