Keeping a journal isn’t necessarily like keeping a diary. Journalling is a more free form of writing — less about recording events, more about externalising feelings. It’s a chance to be reflective, go deeper with your own thoughts. It’s also a place to share what’s exciting you, interesting you, scaring you — taking it out of your head and getting it onto paper. Journalling takes a little of your time but there are definite benefits to journalling.
Writing by hand, in a paper journal, slows you down, allows you to really think and also ensures you keep off screens and distractions.
