Motivation can be hard to come by, especially in the face of challenges or difficult work. When you're thinking about implementing that new idea, or starting that new company or beginning that new regimen -- this is the new year, after all -- it's easy to talk yourself into procrastinating. Or worse, avoiding your goal altogether.
You can't do anything unless you truly believe in yourself and know you can or at least are willing to give it your all. Remember that story you heard when you were little about the little engine that could? A small, little engine was able to pull a big, heavy train over a high mountain. He kept telling himself: "I think I can. I think I can." He believed in himself and was able to do something no one else thought he could.
