Remember what you loved at eight before anybody told you what was cool. That kid had unfiltered taste.

Before taste got filtered through what other people respect, you liked things for direct reasons. The eight year old version of you had no strategy, no sense of what was impressive, and a very clear sense of what was interesting. Most of what got dropped later was dropped for social reasons, not because the interest died.

Make a short list of what absorbed you then, as specifically as you can remember. Look for the underlying shape rather than the exact activity. One of those threads is usually still live and simply waiting for permission.
