What needs to be perfect?

The other day my 5-year-old son was practicing his letters and he brought them over to me, A-Z, and I told him that it was pretty good but that the J and the Z were backwards. 

Then he says, “Oh whatever, it doesn’t have to be perfect.” 

That made me laugh, and although I’m not sure if I agree with him about the letters, it’s certainly true about some things. 

Things don’t need to be perfect.
