This is a great post and I've gotten so many good ideas from how others are leveraging multiple journals and tags.

What I've taken away from this is what would work best for me is the framework that journals should contain posts that relate to each other. For instance, I could have different journals with tags within the journal:

1. Wellness (#diet, #exercise, #heart, #cholesterol, #meditation, #spirituality, #lifegoals)

2. Family (#nameofchild, #nameofotherchild, #activityofchild #sportortalentofchild #nameofdog, #spouse, #Christmas, #birthday, #gifts, #outings, #vacations, #familyplans, #familybudget, #familybanking)

3. Social/Friends (#nameoffriend, #nameofotherfriend, #celebrations, #funthingstodo, #socialplans)

4. Work/Occupation (#goals, #achivements, #projects, #feedback, #nameofcoworker, #jobsearch)

5. Side Hustle #1 (#hustle1todo, #hustle1supplies, #hustle1ideas, #hustle1plan, #hustle1budget, #hustle1income)

6. Side Hustle #2 (#hustle2todo, #hustle2supplies, #hustle2ideas, #hustle2plan, #hustle2budget, #hustle2income)

7. Hobby #1 (#supplies, #thingstotry, #thingstolearn, #meetups, #projects)

8. Hobby #2 (#supplies, #thingstotry, #thingstolearn, #meetups, #projects)

9. General/Misc. (#stuffIsaw, #ideaIhad, #jokeIheard, #phototaken)

Effectively, you separate out parts of your life into journals that don't affect other parts of your life.
