I did the rainbow month last year ( http://365project.org/tags/mw-rainbow17 ), and it was soooo difficult for me and I really struggled each and every day. Probably because I challenged myself additionally to the correspondent colours, to a special theme for each week. So silly! At the end of March 2017 I made a vow to myself, to not even think of taking part of that challenge again. Ha ha, and now I'm at the beginning of March 18, the beginning of the rainbow month,... and here it is a "greenish" kind of picture, and a "concept" in the back of my brain. I do not promise to do the whole month, and I do not talk about the concept,... I just let happen, if it works or not.
