By now you may have seen more than a few columns on the morning routines of today's most prosperous entrepreneurs and business men and women. Some of these people love a good morning workout session, or start their days as early as 4:00 am. Others incorporate meditation sessions before tackling their email inboxes. 

It certainly can be beneficial to learn about the daily routines of today's leaders, but what about history's creative titans?

Many of the world's greatest minds, writers, and musicians had their own uniquely powerful regimens and practices. These four are worth a look:

Marina Abramovic -- performance artist.

Performance artist Marina Abramović is perhaps most known for her work, The Artist is Present (2010). With this work, she sat at the Museum of Modern Art for seven hours daily, six days a week, for eleven straight weeks. Not eating or drinking during her performance, she implemented an evening routine that required her to wake up every 45 minutes for a drink of water. She got up every day at 6:30 am, ate lentils and rice, and had a cup of black tea for breakfast which sustained her during her work. 

Andy Warhol -- artist, director, producer.

From 1976 until his death in 1987, Warhol started each day the same way: at 9:00 am he would phone his friend Pat Hackett to discuss the events of the previous day. He did not leave out a single detail -- in fact, these two hour calls would be the foundation of his memoir, The Andy Warhol Diaries. After taking his two dachshunds for a walk, he would spend his mornings shopping along Madison Avenue, before arriving at his office for meetings between 1:00 and 3:00 pm.

Ludwig van Beethoven -- composer and pianist.

Rising at dawn, this musician started his day with a self-prepared brew of coffee -- exactly 60 beans in each cup. Much of his afternoons were comprised of long walks, while his evenings were spent at the theatre or with friends. Just as he awoke early, Beethoven went to bed early too, typically by 10:00 pm. 

Salvador Dali -- surrealist. 

How's this for a daily affirmation? In 1953, Dalí wrote, "Every morning upon awakening, I experience a supreme pleasure: that of being Salvador Dalí, and I ask myself, wonderstruck, what prodigious thing will he do today, this Salvador Dalí." 

Many creatives and business leaders alike do similar things each day to set up their work for success -- from early mornings, to long walks, and strict dietary routines. But don't forget about the power of affirmations -- consider taking a page out of Dali's book to set yourself up for confidence and success.
