Worst kind of jira ticket is just a link to a document that can be edited anytime. In that case I just replace the link with a new link pointing to the fixed version of the document and inform the author of the ticket/document about it.

If I'm writing something, I'm writing it once. That "prewriting" stuff they teach in schools just slows down the process and makes you overthink your choice of words. I take the same "1 take" approach with code with the idea being to write the best solution on the first try. Why waste time writing something bad just so you can fix it later? That doesn't make any sense.

As I'm writing, I do go back and make changes as they pop into my head. But once I'm done writing it, I'm done unless I notice an obvious mistake after the fact.
