Define your space of interest. Within it, you can talk. Woodworking for interest includes talk of table legs and cabinet making, Wood shavings and sanding finenesses.
But you can also talk from outside the area. Talk about woodworking as one of many spaces of interest. This is meta talk. Not so interesting when about woodworking.
More interesting when about talking. Or about your own pov, or your own entire belief set.
Even more interesting when about whatthe healthy limits to meta should be! Meta-meta talk. The godel point of meta.
