Time for a little celebration around here: we're already past the half of the 30 days challenge I started a couple of weeks ago, and which was followed by a few courageous Steemians. I love these challenges (I think I've done dozens so far, in many areas, from dieting and exercising, to social experiments, or, obviously, writing). They give you a sense of accomplishment and they act like a "gym" to whatever you want to learn: they strengthen your "muscles". At the end of which of these challenges I found myself more balanced, and, most of the times, more "trained".

Part of my commitment in this challenge is to select every day 3 posts participating in the challenge and upsteeming them at full power (around $2.4 at the current rewards pool values).

If you (still) wonder how you can join this challenge, just tag any of your posts with #challenge30days (there's also a link at the end of the article with more information).

Here are my picks for the 15th day:
