My username is fine as it is currently. However, I've been thinking about changing it when I become an adult to make a fresh start. I have a particular username in mind, but I won't reveal it to prevent namesnipes. And I've considered changing it to something related to Kieran (my favorite Pokemon character), but have decided against it because my hyper-fixations tend to come and go.
y'know, I really hated my username and was going to change it right when I hit the 1,200 bells.
Then as I was saving up and sat with the username...it's perfectly fine. I don't want to change it anymore. Then I spent the bells on other stuff instead.
