I don't care for mixes when baking, I really enjoy the challenge of perfecting a recipe. Thing is, I don't expect everyone to have the same enthusiasm as I do for baking. It's taken me years to "perfect" my cake and cookie recipes and to be honest, I'm still always looking for ways to improve them. Most people don't have the time or desire to go though all of this and that is OK.
I think that it is more important to get into the kitchen and enjoy the process of making food and sharing it with your family. My boss posted pictures of her making cookies with her granddaughter, some were slice and bake and some were homemade. The important thing here was a grandmother making memories in the kitchen with her granddaughter not whether everything was made from scratch.
I would love to have the time and ambition to make everything from scratch, but I don't, but I think that I put out some pretty good grub!
