I started a new journey earlier this month. In short, I converted my apartment into a coworking + coliving space and, as a result, I got three new roommates.
One morning, I sat down on my desk and found a pleasant surprise. It was really nothing but it put a smile on my face. There was a message on my MacBook, "Good morning, Sunshine!" (I forgot to take a picture).
It's funny how something so simple can make you really smile. A couple of days later, I found another one.
This one made me smile and wonder for a moment.
I think this is the key to happiness: appreciate what you have today and smile.
