Execution lies in the details
Once the vision for your startup is firmly in place, it helps to tighten up focus. This quote from philosopher William James about “master[ing] the thousand and one practical matters that will ultimately make your dreams come true” evokes the right picture: “I am done with great things and big plans, great institutions and big success. I am for those tiny, invisible loving human forces that work from individual to individual, creeping through the crannies of the world like so many rootlets, or like the capillaries.”
 as summarized by Rob Breszny who would qualify as a philosopher in my book.
