This quote belongs to Sydney J. Harris (1917 - 1986).
All action begins with the "thought" of it first. Looking into a mirror, we see only ourselves reflected back, but looking out of a window we see the rest of the world and our experiences will multiply. Our lives will become truly enriched by our interaction with other human beings and creatures. Education plays an important role in expanding our private universe. To live a productive life, we need to look both inside and outside of ourselves. Explore all the avenues that are opened up to you through education. Then use your creative mind to help solve the problems both within yourself and in the exterior world.
