Those who journal, how do you do so authentically? (How to stop “self-editing” or “censoring” yourself and your thoughts?)

I have tried and failed to journal many times in the past. I always find myself self-editing, avoiding writing certain thoughts or feelings and just overall not being as authentic or honest or genuine as I should be to actually get some value out of journaling. I wish I could get over this “self-censoring” habit because I love reading and writing and really think journaling could be a great outlet for me.

So, I ask, what tips do you have to help write? To help actually get your thoughts and feelings out on the page, without judging yourself or feeling self conscious or critical? What do you write? What do you find helps you write more honestly and genuinely?

Could really use some help and guidance.
