What's the difference between a journal and a diary?
A diary traditionally records what happened; a journal explores what you think about it. In practice the words are used interchangeably and the distinction that matters is whether your entries stay at the level of events or move into meaning — because the reflective kind is what the research on wellbeing benefits actually studied.
The traditional distinction
A diary is chronological and event-led: dated entries recording what occurred. A journal is thematic and reflective, following an idea or feeling wherever it goes, sometimes without a date at all.
Historically diaries were also assumed private, while journals were often written with an eventual reader in mind — travel journals, commonplace books, writers’ notebooks.
Why it barely matters now
Modern usage treats the two as synonyms, and no benefit depends on which word you pick.
What does matter is the depth of the entry. "Had a rough meeting" is a diary line. "Had a rough meeting, and I think what actually stung was being talked over by someone junior to me" is where writing starts doing something for you.
Common questions
Should I keep a journal or a diary?
Keep whichever you will maintain, and try to include one reflective sentence per entry. The reflection is the part associated with wellbeing benefits, whatever you call the book.
Can one notebook be both?
Yes, and most are. A dated entry that records the day and then explores one part of it is doing both jobs at once.
