My garden this year is mostly populated by volunteers, and a good thing too, otherwise there wouldn't be much there. There are several patches of Mexican sunflowers, and a couple of surprise pumpkins (or gourds, perhaps :), and even a cosmos or two. The only thing I planted myself were two rows of peas, in a fit of energy and desperation at the end of May, and a tiny collection of tomato, cucumber, and annual starts that I bought at the farmer's market, which is cheating, but I don't care.
I'm not a very good gardener. I'm not good at imposing order: I hate thinning what I've planted and I almost never pull out volunteers. It's an unwillingness to choose between serendipity and what I think I want. In a way, it's a refusal to take responsibility, and/or to pretend I have control. Before I fall overboard, I'll admit that I do distinguish between 'volunteers' (plants I like) and 'weeds' (plants I don't like), although I'm not very good at pulling the latter either.
The space of my life is overrun with both planted seedlings and volunteers. And I can barely keep up with either one. I met an important mentor because I didn't do well enough on a Spanish placement exam. I found my first job in Barcelona because I got lost in an office building. I got the rights to the Spanish edition of The Macintosh Bible after asking for permission to publish just a few tips. I got invited back to the US in the middle of a concert of the Rock Bottom Remainders. I agreed to do the HTML book so they would let me do the Netscape books. Oh my. But I knew I wanted to do EPUB as soon as I saw the iPad :)
And everything is so interconnected, and gets more and more so. The peas climb up my volunteer sunflowers, and I go to Barcelona and learn how to publish books and then 20 years later publish books about Barcelona. I never know what's going to come out and how tightly to hold the rudder.
