Social media implies we should be happy all the time. I may not be engulfed in happiness all the time, but as long as I don't feel sad I feel I am doing ok.
I am doing so much work to invite happiness into my life. I feel happy. I feel content. But we can't all live with a heightened state of happiness that we may feel doing special things, from holidays, to events, to the arrival of new furry friends etc etc ...
And - like you say, I believe passionately in creating our own happiness.
There is a wonderful cartoon with a stick figure clutching a pot that reads happiness. And another stick figure asks where he got it from as he has been looking for it everywhere. He simply replies saying "I made it myself".
p.s can you tell I am waiting for a delayed flight. It's great cause I can finallly catch up all on all my Medium articles! :-)
