Whether your career does or does not center around innovating or creating new things, it's not always guaranteed that you will feel the necessary flow of creativity. Sometimes the river runs dry, leaving you uninspired and perhaps even frustrated that ideas are not coming to you as easily as they used to.

If you're lacking imagination, turn to the brilliant words of these creative masterminds for motivation and inspiration:

1. "We don't make mistakes, just happy little accidents." -- Bob Ross

2. "Don't think. Thinking is the enemy of creativity. It's self-conscious, and anything self-conscious is lousy. You can't try to do things. You simply must do things." -- Ray Bradbury

3. "Creativity is just connecting things. When you ask creative people how they did something, they feel a little guilty because they didn't really do it, they just saw something. It seemed obvious to them after a while. That's because they were able to connect experiences they've had and synthesize new things." -- Steve Jobs

4. "Creativity is allowing yourself to make mistakes. Art is knowing which ones to keep." -- Scott Adams

5. "The artist is nothing without the gift, but the gift is nothing without work." -- Emile Zola

6. "Draw the art you want to see, start the business you want to run, play the music you want to hear, write the books you want to read, build the products you want to use -- do the work you want to see done." -- Austin Kleon

7. "Don't think about making art, just get it done. Let everyone else decide if it's good or bad, whether they love it or hate it. While they are deciding, make even more art." -- Andy Warhol

8. "Creativity comes from trust. Trust your instincts. And never hope more than you work." -- Rita Mae Brown

9. "The worst enemy to creativity is self-doubt." -- Sylvia Plath

10. "We have to continually be jumping off cliffs and developing our wings on the way down." -- Kurt Vonnegut

11. "In order to be open to creativity, one must have the capacity for constructive use of solitude. One must overcome the fear of being alone." -- Rollo May

12. "Making the simple complicated is commonplace; making the complicated simple, awesomely simple, that's creativity." -- Charles Mingus

13. "A wonderful emotion to get things moving when one is stuck is anger. It was anger more than anything else that had set me off, roused me into productivity and creativity." -- Mary Garden

14. "The chief enemy of creativity is 'good' sense." -- Pablo Picasso

15. "The secret to creativity is knowing how to hide your sources." -- Albert Einstein

16. "If you hear a voice within you saying, 'You are not a painter,' then by all means paint, boy, and that voice will be silenced, but only by working." -- Vincent van Gogh

17. "All profound distraction opens certain doors. You have to allow yourself to be distracted when you are unable to concentrate." -- Julio Cortazar
