I've always loved being out in the garden, and would create one wherever I've lived. It's not that I'm addicted to nature, I just couldn't live without it.
If it's growing, I'm fascinated. If I can propagate it, even better - even plants that normally don't like to make more of themselves give up when I get a hold of them.
Xeriscaping and gardening with hardy succulents is the best thing that ever happened, and now I use Sempervivum and Sedum (among others) to create succulent crafts like globes and mosaics, and to plant into hypertufa creations.
