That sounds weird. I'm usually close to an hour early. I take two buses so I'm either 50 odd mins early or I'll be a few minutes late. I like being early because I can collect my thoughts, have a cup of coffee, and edit what I brought in for her to read ;-)
It sounds like you're early due to circumstances, rather than perfectionism - is that a fair assessment?
Do you think there's any value in this? Or can you amend it to focus on a different aspect of your perfectionism?
