Software programming is a craft. To more you practice and learn, the better you will become. When you're beginning, you do it a lot, and you keep on practicing.

As time goes by and your business grows, you get distracted by everything around your craft, and you take more time to help other code than you do.

You have to decide where to put your time. If you don't code yourself, technology will evolve, and you'll soon be irrelevant to other developers. What made you a great programmer was practicing your craft. New technologies are born, new ways to deliver software, and you need to keep on practicing.

This is where katas are helpful. These daily exercises are a way to keep you on the ever-learning path of software craftsmanship. If you don't use a specific language at your job, no problem, keep on doing katas in that language.

Do Katas inside a side project or use a specific tool like code wars (my profile is here). The goal is to continue doing what made you start this profession in the first place.
