In August 2017, a few of us were inspired by the video at the link below. It's the story of a woman who went to the gym 100 times to try to get herself out of a rut. I saw it when George Takei posted it on Facebook along with the question, "What would you like to do 100 times?"

Her video was part of a larger movement online called "Give it 100" which, as far as I can tell, is now defunct.
I decided what I wanted to do 100 times was work on my fiction writing at least 30 minutes a day. The times do NOT need to be consecutive. Since I knew I would miss a lot of days here and there, I was aiming to complete my 100 days by January 15, but I actually ended up doing 110 times and finished them in mid-March. Now I'm working on another 100. I completed #6 today!
Others have worked on other things - nswef completed 100 times of 6,000 steps a day and is also doing some writing. Chicken Lady got 30 days in her studio in November and has also counted swimming and other things.
Anyway, if anybody else wants to join in for 20, 30, 100 or however many times of something, please do!
