"Perfection is the enemy of the good"

Very few things in life can be divided into what is good and what is bad, just like the world is not black and white. There are numerous shades of grey. In fact, there is a whole spectrum of colors and shades, so why should we limit ourselves to consider only two. That being said, we have to define some behaviors as good and others as immoral in order to keep order in a world with so many differing and contradicting opinions. Furthermore, some actions, people, qualities, days, etc. are just inherently more "good" than others. For example, giving is better than stealing, Gandhi was better than Hitler, to be full of love is better than to be full of hatred, the last day of school is better than the first,....  But how do we determine these? Similar to truth, determining the good comes from a mixture of analytical thinking, learning from your elders (parents, teachers, distinguished individuals...), and listening to your own emotions and gut. I believe that with the good, the personal side versus the intellectual side is essential. You can stop to hold the door open for an elderly person for a number of reasons. You can hold it open because you feel that society would deem you rude in not doing so, or you can hold it open because you would deem yourself rude in not doing so. Either way, you are doing a good deed, but which is more sincere? Good is many things. It is justice, it is kindness, it is that warm fuzzy feeling in your chest when you drink warm tea or help a stranger pick up their spilt groceries. Something or someone that is good does not have to be flawless. Often it is the dark, rough patches that help us notice the bright and smooth and appreciate them.
