More than 10 years ago on a newsgroup or mailing list (I don't remember which) I was discussing scrapbooking--you know, cutting up your photos and combining them with colored papers, stickers, and pens into attractive pages that tell stories. Some historian or archivist jumped into the conversation to deplore this practice, telling us that we were evil and moaning that it would someday make her job (and the jobs of people like her) harder because sometimes it's those very peripheral details that tell the most for history, and snipping the photos was decontextualizing them. And she was right--it will make their job harder.
But she wanted everyone who was scrapbooking to arrange their lives to accommodate her life goal, learning things from photos. The rest of us had completely different goals in life, and cutting up our photos aided our goals. Once I recognized that her perspective wasn't mine, it was easy to understand but dismiss her concerns.
I don't believe you need to drop everything and figure out your goals in order to shape your life to them. I mostly work in the peripheries myself; straight ahead is an unknowable vortex, but all around the edges and in the depths are the pieces that flitter and vibrate and soak up information and practice, and aggregate into the collage that is my goals. I'm making choices all the while that perambulate, dance around, spiral in and out towards my goals. And when I discover them, I'm usually already far into the practice of achieving them.
If you aren't sure what your goal is, maybe you are approaching it cattercorner or widdershins. Maybe you're sidling up to it for good reason.
