Perfection is acceptance
I was putting up some new curtains the other day and anyone who has ever put up curtains I'm sure will agree with me that getting the crinkles at the top just right is by far the most difficult aspect of this particular activity. Now because they were new curtains and I know they'll be there for a very long time I was doing my utmost to get the crinkly bit at the top perfect. I'm not exaggerating when I say I spent about two hours trying to get the crinkles even so that the curtains hung perfectly. However as my arms got heavier and my neck got creakier I thought that perhaps with crinkles, perfection is acceptance.
We consider something to be perfect when we consider it to be just right. Over time when I look at my curtains I'll get more and more used to the fact they are (to my current annoyance) a slightly less crinkled at the sides than in the middle. However as with everything, I will get so used to it that how they are will become how the 'should be', and how they are will become perfect.
It's like how some people must have a table at a certain place in the room otherwise its just not right, its not perfect. They've got used to that table in a certain position that it has become the 'perfect' place for it. If all the public exams I have ever taken in the past suddenly became full marks, some people would say those marks are more perfect but they wouldn't be perfect for me. I'm comfortable with the marks I have and I've planned my life round those marks, it would be odd at distinctly uncomfortable if I suddenly got straight As. (or maybe I'm just telling myself this to make myself feel better!)
So my point really is, if anyone is worried about they're curtains, exams results, house, hair colour, over time they will* become perfect. Isn't that a nice thought?
*sadly, you probably have to think like me for this to work....
