I love the convenience factor with using Google Drive and how I’m so excited to reflect and see what are consistent driving forces for my happiness. I decided to track my happiness because recently I’ve come out of a long relationship and was holding myself back in a lot of ways in my life.

My last journal was stolen, so I'm really happy with the weekly back-ups and overviews. Writing a diary has never been this easy and I'm having a lot of fun using it!

The free trial really helped me experience how powerful this is. My dashboard is very revealing already. The happiness factor analysis shows me exactly what I should focus on in my life if I want to be happier.
