See if you relate to the happiness factors:
Connecting - Relationships are essential for happiness. Connecting and sharing with other people keeps us going, even in the tough times
Gratitude - Learning to be thankful for the big and the small things in live. In comparison, most people have a great life. Living a life that sees the glass half full rather than half empty makes for more happiness.
Passion - Living what you love obviously leads to more happiness. Even when there are things in life that aren't so fun, an unfulfilling job, finding ways to live your passion will lead to more happiness. Time spent, even minutes a day, doing the things give us pleasure, feed our soul, and give us meaning are important to being happy.
Seek simple pleasures - At a certain age, most people realize that money doesn't buy happiness. Learning to appreciate and treasure life's simple pleasures - a beautiful sunset, a really great cup of coffee, watching children laugh, puppies play, appreciate a piece of art or music - these pleasures are priceless.
I didn't realize it, but this is my 100th post. I guess it was fitting that I wrote about happiness gained from blogging - a coincidence, but very apropos.
