The idea came to me when I thought about how, when I go for a walk, it is much easier to move forward when I have the sun behind me lighting the path on the way out, as opposed to when I come back, because I have it in front of me and it blinds me.
I thought that many of us have ideals that are very ambitious and “brilliant,” perhaps so much so that they blind us like the sun when we look at it head-on. So, I think it’s best to have these ideals as a way to “light” our path and guide us to our true goals.
