diary 

A notebook containing one's personal thoughts, feelings, plans, attitudes, observations, and the like. Written in usually at frequent intervals, usually but not always kept private.

I've kept a diary since I was 7. It's fun to read later.

Diary 

A recording of one's inner thoughts and emotions. A place for one to vent their emotions/thoughts on. And also, eventually a place for someone else to read and realize the past thoughts of the previous user.
