The ingredients might not taste very good on their own, but without all of them the cake isn't very good. The ingredients are the things in a person's life, like experiences or struggles. These ingredients are what makes the cake, well, The Cake. You wouldn't be you without those ingredients, and a cake won't be chocolate unless you add the cocoa powder.
Also, there are all sorts if cakes out there, and each and every cake is perfectly unique. You may not be an "angel food cake", but you might be a red velvet cake.
You cannot even begin to compare cakes. I mean, who's the ultimate judge of the best cake? You might prefer chocolate, while another person prefers Lemon. Not everyone likes the same things. Just because someone doesnt think your all that great doesnt mean someone else wont, you just might not be that person's flavor.
It is currently 3:54 A.M. and I felt I had to share this with the world.
