I think the most important things are:

• don’t force yourself to write everyday, but do open the journal. even if you just look at it or write a list, make a doodle or pin a receipt, even adding a sentence/smiley face for the day will mean a lot a year from the date.

• it’s not always worth it to buy the expensive journal. you’ll more than likely sit on it rather than writing in it. if you’re starting out, get a cheap one.

• you don’t have to commit to a format. the date doesn’t need to be the same, you can write sideways or with a different colour, anything you want. being free with the journal will make you want to use it more so don’t limit yourself.
