I'm a bit OCD also and try my hardest to do the best I can at the skill level I am at. If I rip a point or seam twice for the same thing, I usually leave it on the third try & chalk it up to inexperience. Too many rips and I feel I am doing more damage to the material. Now that being said, I will always turn blocks if wrong, unless it is quilted, and then it is a design decision. I'm a lot easier on myself as I age. Quilting is supposed to be fun and most non-quilters will never see it. Now, if a picture is hanging crooked or the blinds are uneven, those are corrected LOL
A funny story: Our son and both his kids are like this too (he is a middle child by the way). He had just gotten through changing our grandson, almost 2 1/2, and put new pants on him. Our grandson said, "I need a new shirt too." When asked why he replied, "Because my shirt is orange and my pants are green and they don't match!"
