Writing a private journal seems to be time consumed both on writing and reading.
You may write a bit of information or feeling so many times a day then one day you may digging deep down into what you have written for years.
Stuff like that you enjoy reading it again so much enough, that why I can say it worth its.
Write it now, to enjoy it later. ^ ^
I’m writing this after a 2 whole years of writing a private journal everyday.
