I've found the same experience while working on articles/blogs for this site. I overdeveloped mathematics and logic skills early in life and neglected writing and creativity. I read blogs I wrote 8-10 years ago and it's night and day compared to my writing now; it's like I was fucking illiterate. Never stop growing or learning.
However, I want to make a slight improvement on this statement:
The incentive structure on Steemit encourages individuals to produce and create their best possible content, while being mindful of and disclosing their own experiences.
I wrote a 3000+ word blog on one of the most interesting stories of my career: A Poker Paradox: Sometimes Winning Can Hurt More Than Losing. Unfortunately I chose to do so before I had built a large enough following, so the rewards don't match the effort that went into writing it and the intrigue of the story.
Steemit truly encourages individuals to participate in the community and cultivate a following on the forum and only afterwards, then produce and create their best possible content.
As always appreciate your work and hope you continue growing and learning as I have.
