Where is happiness? I think that a vast amount of happiness and contentment can be found in gaining insight into your own person and, consequently, growing into your best possible self.
"We live in deeds, not years; in thoughts not breaths; in feelings, not in figures on a dial. We should count time by heart throbs. He most lives who thinks most, feels the noblest, acts the best."
This is important (if not nearly impossible) to cherish the down-lows for giving you a more complete picture not only of life, but of yourself. Everyone wants to live a life well-lived, but life is not all rainbows and butterflies (although, I would settle for butterflies!). As most points regarding happiness are, this is much easier to understand and describe when things are going well. But, I would argue, that this is also the best time to delve into how I should approach life, obstacles and pleasures.
