How to make painting concrete porch steps right way

In the past three summers, I painted 2 out of 3 of our concrete porches. The first one that I painted in 2019 was our large back porch. Unfortunately, I didn’t do enough research ahead of time and I completely botched the project. Though the end result was beautiful, the road to get there was a huge mess with pivots and setbacks, and lessons learned along the way. When I decided to paint the second porch in 2020, I was ready for redemption!
