I think some people are born with happy genes. Just like some people are born with sad genes. For every person who sees the glass as half-empty, there is someone else who sees the glass as half-full. For every person who can laugh so hard at a joke they cry, there is someone else who finds it lackluster and inane. For every introvert, there is probably an extroverted counterpart.
Finding an equilibrium in life is difficult. Maintaining that equilibrium even more so. I don’t want to be an intellectual snob. Neither do I want to be mindlessly groveling for something, anything. You said, “In the middle lies the path of virtue.”
Show me the way. Or better yet, walk with me for a while.
