Gerd
I agree with Gerd's thought process at breaking this down to practicality.
a. We could focus on the end result (goal) for naming each of the category. Example: Sleep better.
b. Or we could focus on the 'means-to-the-end' angle for any and every goal that humans may go after. Example: Have a healthier Lifestyle.
Both a. and b. could mean the same path but one tells me the goal and the other tells me what I should be doing to achieve a few specific type of goals including 'sleep better'.
Some people relate faster to a goal, some to the process itself. Thatswhy I think we need to do both and create an internal mapping to do well researched correlations.
Some people may not understand the correlation between ''Increase productivity' and 'sleep better'. If I want to sleep better but all I see is 'increase productivity' then I dont have a goal based community that's appropriate for me.
Also, not every detail and habit creating elements of "Increase productivity' is relevant to "Deep Focus" goal. So people who want to only learn about focusing deeply when they want to may end up listening a lot to 'sleep better' conversations too and they may feel its irrelevant and have to come across or listen to a lot of them since its under the broader catagory of 'Increase productivity'. Especially if they are already sound sleepers.
It may be true that sleeping better IS important to the ability to 'deep focus', but unless as a (novice) user I dont already make that connection in my brain, I may feel its irrelevant. So I think we gotta do both and let people associate with goals as they see it and use AI to weed out irrelevant content.
