Cake is happiness! If you know the way of the cake, you know the way of happiness! If you have a cake in front of you, you should not look any further for joy!
You've got this life and while you've got it, you'd better kiss like you only have one moment, try to hold someone's hand like you will never get another chance to, look into people's eyes like they're the last you'll ever see, watch someone sleeping like there's no time left, jump if you feel like jumping, run if you feel like running, play music in your head when there is none, and eat cake like it's the only one left in the world!
If you wait for a cake to be given to you so you will be happy- then you will be happy when someone gives you a cake. But if you buy a cake (or bake one) for yourself so you will be happy, you have found the way of happiness.
