"Life isn't about waiting for the storm to pass, it's about learning to dance in the rain."
I think happiness is mostly a choice. Of course, you're not going to be happy during all difficulties, but learning to smile outwardly and inwardly is a great life skill that makes things more manageable.
It is. But, most of us are not enlightened enough to reach a level of perfect contentment and happiness. For me, it's the trials and tribulations that make me understand hapiness; as much as the hapiness itself. You would never search for the silver lining if you had never seen a cloud.
