How to document life events (77 years worth)

I’m new to Joplin and hope this is the right place to ask a question. I want to document life events. Seems simple but I don’t want to start creating notebooks, subnotebooks, tags, and notes and find out later I was a dope to do it the way I did. I’m not clear on the structure I should use. Dates will be the key I guess but sometimes it may be just a year or a year and a month for an entry. I do know that I can use tags to easily find related stuff ( Navy, Argentina, California, etc.). I guess there are templates to make entries consistently? And there’s plug-ins to maybe visualize the data in different ways? Any and all help will be appreciated!
