Happiness is weird and different for each culture. If you have time I do recommend this Ted talk about the science of happiness.

If you feel happy while reading or fishing in a creek or risking your life free climbing - those things are all valid. Tho the last one in my mind isn’t really sane and 100% healthy mind.

The only thing is not acceptable is when some twisted people get joy from others suffering. But technically speaking their happiness is real - even if they are not fit to be part of society.
