I'm not sure I have an answer for your problem per se, more like a comment. I think its really awesome when I hear about anybody wanting to start a practice or a more active hobby. Whether its creative, meditative, athletic, for work, etc. I think that its a wonderful thing to have and do, and challenge oneself with. It's not always easy, it's not always fun. But it can be rewarding. And it can be fun. That's the point!! I myself have a bunch of hobbies. My favorite one currently, is knitting. I have a meditation practice that is kind of collecting dust. It makes me feel better usually and I'd like to get back to it.

I like Key Tones' idea for you. Carrying around a small recording device or phone with one already on it. Good idea.
