As you found out, cake civilians think anything you do is beautiful because they can't do it.
I always have a problem with people who claim to "strive for perfection". As far as I'm aware, there was only one "perfect" person. It was ... oh heck, what's his name? .... I always forget it ..... you know, that one guy? ..... they made a movie about him ......
Oh Yeah!!! JESUS CHRIST! And you know what? I ain't Him!!
I strive to make a great looking cake. Of course I want it to look as nice as possible, but even God makes an imperfect flower now and then!
Enjoy the process; enjoy the creativity; enjoy the appreciation of your friends when you give of yourself to help celebrate their special event.
