There are multiple ways in which we can build up our minds to be more creative. One way NOT to become more creative is to do everything the same old way. Working or studying all day everyday can get boring. We may get into a 'rut' and become work/school/family zombies. Looking at our jobs, our studies, or even our lives in more creative ways helps us do all these things better.
Sam Walter Foss wrote a poem in 1895 that we should take into heart.
