It's pretty nice challenge to start with. Recently I also started to write it down, but without using Steemit.
It was to write down in a paper with 5 thinks you are grateful for . It was challenged to write on a paper instead of online social media simply because it was only a 5-10 minutes challenge and it was to aim for the mind to quiet down and reflect early in the morning after waking up and freshen up, before the start of a busy day.

I wish you all the best with your challenge and I hope more people will take on the challenge as there are too many people who tend to look at the bad things of life more than the good.

ps: you should check out #gratefulvibes too. They have similar movement which I spotted some time back early this year.
