I have no idea but it is a surprise to see a friend here! Why not be happier about things! I am happy even when I am sad!
If your life's purpose is solely to enrich your own life, you'll quickly find that your life is shallow, meaningless, and endlessly miserable. Everybody needs a goal for their life that's bigger than themselves and also that goal should be achievable within a lifetime. A person with this kind of goal will find meaning beyond their circumstances, they will conduct their own life to work towards that big goal even when their daily circumstance is imperfect (it will always be imperfect).
