I do this on a small scale. Couldn't agree more. It really does bring a lot to your mental health.

I'm sitting in the kitchen writing this staring out the window at a nice juicy tomato with my name on it. I'm having it for lunch in my sandwich.

You do have to get used to failure. For example, it's July an my butternut plants are only 2 inches tall an have no chance of fruiting ever.
