You'd be surprised with how many lessons you can take away from even a short period of taking a new position.
For instance I had done very limited management in my past. When a new project came up the company I worked at they had made me lead the project which essentially meant developer + manager. This employer also had the habit of under staffing teams while pushing very aggressive timelines. This lead me to try to manage a team of 6 while also coding around the clock for several months. When it came to review time I was a mess; I hadn't paid enough attention to my team, I was constantly scrambling for tasks, trying to find ways to help where necessary, etc. It was an incredible trial-by-fire.
When it came to my second stint at the same position for a new project I was ready. I gave constant feedback in real-time, I was able to keep on top of tasks, my meetings were more streamlined and I was able to estimate things far better; I did a 180 and became much more effective.
