A simple, maybe idealistic, view on beauty that I agree with 100%. If one does not look internally for happiness in their lives, the external will convey ugliness. I also think happiness is pretty subjective and over rated. I do not think being beautiful externally or successful make us happier people (maybe lucky or blessed) but even the most beautiful or successful people can be unhappy or discontent with life. To me, happiness is being grateful no matter one's circumstances. With gratefulness we learn to be content, a mark of true happiness.
I'm grateful for life. For living and breathing. For being able to enjoy a beautiful sunset. For being able to hear my children's laughters. For living through a painful past and not having that past define who I am. For seeking to thrive from my past. I pray that you will define your own happiness and seek contentment.
