IMO code katas are a waste of time. Practically speaking, prolific development means getting large chunks of the system done quickly, and the best way to do that is to reuse what others have done. Don't code your CSS from scratch, use Bootstrap or similar. Don't create an auth system, use the one that comes with your framework. Counterintuitively, don't automate all the things until that automation is sure to pay off. Sometimes manually testing something is just faster, if you only need to test it a few times before the code never changes again (when was the last time you rewrote your password reset flow?) To get prolific, don't do katas. Katas are the same problem solved in different environments. Do different problems in the environment in which you are productive. That is what will make you better and faster.
