The idea of 'the pursuit of happiness' frustrates me. You spend your entire life pursuing, and none of your life happy. Why go on a conquest to a mythical, idealogical world that you will never reach? Earthly life will never be perfect. Things will go wrong, you will have faults, but you have to learn that THAT'S OKAY. Look for the good in your life. Count your blessings, serve others, and forget about perfection. Here's an idea: you don't have to wait to be happy!
So don't waste your time in the pursuit of happiness.
Be happy right now.
