If you just keep writing, will you get better? This is the topic of a recent post by Jane Friedman (https://janefriedman.com/practice/), drawing from the informative book, Peak, by Anders Ericsson and Robert Pool.
The reality is that you need the right kind of training to improve. Doing the same thing over and over in the same way will not yield change in the form of improvement.
Ms. Friedman explains the salient points of the book. If it enlightens and intrigues you as much as it did me, you might also want to head on over to Amazon for this excellent resource!
