A Message To Those Thinking About Switching Characters

[2B]

But if you continually switch you will never push past that plateau of the veteran character, and you will never grow as a writer.

While I agree with the majority of the post, I also feel that the above statement is not necessarily true, for sticking with a character is hardly the one and single way to grow as a writer. What it does mean however, is that the characters won't grow, if you keep swapping them away.
You, as a writer, however?
You can grow a lot from simply swapping characters.
As someone who has made multiple swaps and has contemplated more swaps than one could possibly even imagine, I can say this:
You can learn a lot from swapping, and/or contemplating swaps. You can grow from them. And you can grow more than just as a writer; You can learn a lot about yourself along with it.

Across my swaps, I have learned a lot about myself as a writer, and grown with each discovery.
For example; when I was swapping away Arturia, and went through dozens of options for characters for swapping; I eventually reached the despair of "Maybe there is just no fitting character for me."
But at that dark hour, I made a decision; I would not give up, if I learned something from each character draft.
Once I would stop learning something from each draft of character? Then, then I would give up.
Then it would be pointless to continue, for there was nothing learned, and my time was wasted.

And with each draft, I learned more about myself especially as a writer. And it was only through those discoveries that I made the breakthrough of finding a character for me; Ahri.

So, in my opinion, the statement that you will never grow as a writer if you do not stick with a character, is blatantly wrong, even if a lot of the post is agreeable.
