Inspiration fading away?

Inspiration is really elusory, difficult to trace and abstract. I have no idea how to catch it. It can't be controlled by ourselves. Recently I found that I was short of brilliant ideas during the work. Seems most of time, just a blank sheet. So annoyed. Maybe due to living comfortable life, so that I seldom thought anything over. My life falls into a set routine. I make a narrow circle for myself. As a matter of fact, for a long time, I haven't read a book carefully. TERRIBLE....
