I make a habit of always typing the opening and closing elements of a block before putting the contents in. As I like to nest things, this makes it easier for me to make sure everything is paired. For example, I will first write (), and then go back to it and put in the contents of the parens. Same with quotes, or a bunch of others. I just did it with a salutation and signature on an email, I’m not sure if this is a good thing.
