If it is easy, makes you smile, and does not hurt others (people or animals), then rock it.
We watched the dolphins for at least an hour. Every time one of the big, shiny gray fins and dull silver backs would roll above the waves, Nicole practically squealed with joy. The dolphins were fun to watch as they frolicked just a few yards from the boardwalk at John’s Pass. Nicole said, “I don’t know what it is about them but they just make me so happy!”
A couple of hours later my dad called me to chat about their visit next week. No joke, just before we hung up, he said, “Hey, is there somewhere we can see dolphins? I love watching them. They just make me happy.”
If it does not cause pain or suffering for you or others and it makes you smile, then you have met all criteria for happiness. Rinse, repeat often, and enjoy.
