I capture a selfie moment with lively dog (picture shown above).
(We have many emotions, unless you are a robot. In the texting world, there are not enough emojis compared to our "real" emotions.) For instance, I was not the happiest person in the world when my sister died unexpectedly, tragically.
(Knowing my sister, she does not want me to mourn her loss. Instead, she wants me to be happy. If I am happy, she will be happy as well.)
How can you be happy?
Go with what makes you happy. Go for your happiness.
