In war as in war! 
Post 1 article with a photo of your life every day for one month and use the tag #monthlyauthorchallenge for these posts.
You don't have to add a detailed describtion to your photo article and it can be a quick photo post with Steepshot for example too. (But don´t forget the #monthlyauthorchallenge tag!)
The photo of your life doesn't have to be up-to-date, but not older than 1 year.
To make it more comfortable for everyone, you don't have to nominate someone for the challenge every day in your daily post. Nominating is voluntary, but to share this fun, I would suggest to nominate some other Steemians from time to time, so that you can do this funny challenge together.
Your challenge ends when you reach the Monthy Author badget on steemitboard.com and then just make a final post that you finished the challenge. 👌🏻
That's it, just have fun and if you like, share this challenge too and let's become Monthly Authors. Everyone, Steem On!
