There's No Perfect Moment. Now And Today Is All I've Got

My friend came and visit me yesterday, the thing is that I've never met before and she will stay at my place for a while. If it was me in the past then i would panic because everything is not perfect – my place is a mess, I'm still wearing braces, I've got oral ulcer, there is a bunch of acne on my face recently. These things aren't big deal but they would destroy my confident. But the question is "Why would i feel that way? Why do i feel so insecure about myself? If these things define me? Are they in my control? Do others feel the same about them? Why is everything always about me?" and the most important one "Why did i invest so much into something i couldn't control? Did i just make something out of my control into my identity? What does it tell about me?"

I spent 3 days cleaning the house, tried curing the oral ulcer, re-appointed my dentist 2 days earlier but the braces got uglier, the night before my friend arrived, i got a bruise on my mouth. Basically, i tried everything i could to make me feel the best, but i didn't panic this time, because i realize that "it's never enough, it's never the right time to do something, i just do it out of the blue, as long as i detach from the expectation of things that are out of control, I will be fine". Keep spending every "now" moment is not a wise strategy.

If all the things listed above are somehow in my control, i will eventually find something else to worry about. Now, there's another scenario just came to my mind, if everything is okay from my perspective, i don't have anything to feel insecure about when my friend arrive, but then my friend don't like something that i never thought of, what i should do now?

I've always know that idea from Stoicism which we do not embrace things outside of out control but barely practice it. Now, come to think of it, it suites the situation more than the idea of "no perfect moment and now is perfect". Because under any circumstance, when I know that things are always out of out control and will always be that way. Then there's no perfect moment when we take account of these thing.
