In his bestseller, Rich Habits: The Daily Success Habits of Wealthy Individuals, and Change Your Habits, Change Your Life, Thomas Corley studied over 1,200 self-made millionaries and found similar patterns and behaviors that can be read about here. According to a Business Insider article, however, the most common behavior he found was that these wealthy individuals spent atleast 15 minutes a day 'thinking' in isolation, brainstorming.  This, Thomas suggested was the key to their success.  

"Brainstorm...take me away from the norm..." as the lyrics go from 311's song titled Amber, is not only a healthy behavior for business success, but also can be applied to creative success for artists.
