It's a great sport! I retired from consulting and became a tennis teaching pro and high school tennis coach, but I also got my pickleball certification and try to play a few days/week during the winter.
It is much more approachable than tennis. It suits a variety of athleticism and is quicker to reach a competency where you can play and have fun. The concept of "open play" also makes it easy to get playing time with a variety of skill levels.
Several good pros on YouTube/Instagram if you want to hit the basics. Tyson McGuffin is my favorite, but I also like Enhance Pickleball, Brionnes, Simone Jardim...and a handful of others.
