I've been gardening for about the past year and I'm obsessed with it. It's fascinating. I can't garden at my apartment so I've joined my city's community garden and work on a 4x12 plot over there. Right now I've got two eggplant plants that are producing the most beautiful eggplants I've ever seen. I have my second batch of compost going, and I just started as a volunteer manager at a small butterfly garden.
I had wanted to start growing vegetables for a long time and I really lucked out finding this community garden. There's new stuff to learn everyday, whether it's repairing soaker hose lines, promoting the growth of beneficial microbes in the soil, or spraying with organic pesticides (it's an organic garden). It's so relaxing to go over there on a Saturday and get work done in the sun. I should add that I'm in Florida so I can grow year-round (although winter growing is much easier than in the summer). It also helps me develop more patience, as it's obviously super delayed-gratification (I'm an impulsive person and it's good for me to have to wait 3 months to see the benefits of the things I do now).
I regret that I can't really travel anymore. That used to be a passion of mine. Now it's just too expensive. I also regret that I've been too lazy to work out the last few months. That'll be a New Year's resolution.
