This is my first step to beating perfectionism

I've always struggled with being strict on myself. Whether that'd be academics, creative endeavours, big or small decisions... There is always a mental fog that blocks me or slows me down. By A LOT. When I say a lot, I mean that most times than not, overthinking about doing "the thing" takes me longer than actually doing "the thing". But what is it that makes "the thing" perfect? In fact what is it that makes the thing terrible? Who is to say?! Are those criteria arbitrary? Are they imposed on us by parental figures growing up? Society? Culture? Education? Then again, will there ever be a consistent, reliable, and even objective measure or perfect? When I have a deadline, something to present to the world, or even a decision to make i will go through it in my head again and again and again and again I will find a way to convince myself that not only is it not "perfect", but it is actually terrible. I am very good with finding reasons why something I produce won't be good enough. I think that it is kind of a coping mechanism, I feel a sense of control doing it, and I sometimes feel like it helps me in some ways produce a better outcome. No matter how much my overthinking seems like it makes that mental fog go away, and helps me towards my goals, all it does is waste my energy and time on the wrong things. So, instead of being so strict on the quality of the things i'm putting out there, why am I not strict on actually putting myself out there? On not being afraid to express myself. To share my story on a website. To make that decision - however big or small it might appear, to me, to the world. However messy, rushed, flawed, boring, irrelevant, uninteresting, tedious, dull, disengaging and uninspiring it may sound... Although a tiny step, me writing this paragraph is me forcing myself to not only embrace imperfection, but to also understand that what I consider imperfect, might be someone else's perfect. And if you, reading this, found that this inspired you in some capacity, shape, or form, then I am glad that my story is far less than imperfect, and I challenge you to share yours... :)
