1.) Lemonade. But it must be sweetened with honey and I insist that it have a splash of rose water (or orange blossom water). This is not for everyone, but for this gardener, it's key to my overall happiness. (Oh, and if you're wondering, yes, it might smell like to soap.)
5.) A place to crash. For years I'd avoided using this amazing vintage chaise but as a converted chronically ill gardener—who is currently in much better health—I plan to use it more now than ever because I'd like to continue being happy and healthy.
7.) Nail polish. I simply cannot say enough about how much better I feel when I'm a complete and total dirtball, with crisp and dry hands, and then I look down and I think, "Damn, those look nice at least."
