Your level of happiness today and every other day will ultimately be determined by your actions. Actions as you respond to fate.
Happiness is not determined by what you see or hear on the news.
It is not determined by another that might be rude to you.
It is not determined by winning a contest or moving another day closer to reaching a milestone.
It is not determined by what you chose purchase as a reward for yourself.
Any satisfaction from these fades away quickly.
Your happiness is determined by the pattern of your actions. Act according to find satisfaction with how you navigated the day.
Take satisfaction in the actions taken that you are the most capable of.
“Those obsessed with glory attach their well-being to the regard of others, those who love pleasure tie it to their feelings, but the one with the understanding seeks it only in their actions.” –Marcus Aurelius —
