Old journals: Keep or throw away?

I have written in journals for much of my adult life and am feeling conflicted about throwing them away to clear out physical space and also the old energy/thought patterns contained in those journals. I don’t go back and read these regularly, but when I contemplate throwing them away and look through them, I feel conflicted. On one hand, they remind me of times in my life that I may forget if I throw them away and I feel sentimental. On the other hand, some memories are painful or represent old thinking that I no longer want to embrace and keep me focused on the past, instead of the future.

I would love some help with this, as I’m feeling a bit stuck.

Thank you!
