Let’s try it to be sure!
A couple of years ago I saw my friends posting about #100happydays, and I decided to try it with a friend. Since we did not feel like sharing our private life details with everyone in the world, we modified the original challenge. Instead of posting everything on the social media, we sent e-mails to each other with pictures and with a short explanation. Every day for 100 days in a row we found at least a moment of happiness, satisfaction or joy. The project was so successful that I decided to repeat it with another friend next year and right now I am doing my 3rd challenge!
