I'll admit it right off the bat, I'm a hoarder. I'm not like a crazy hoarder of just junk, I'm a memory hoarder. I've got diaries and pictures dating back to junior high and probably further than that. Do I really need those things? Probably not. Am I hesitant to throw them away? Definitely. If you've noticed a lot of items you don't use or need at all but can't throw them away I recommend reading "Spark Joy" and "The Life-Changing Magic of Tidying Up" by Marie Kondo.
Even check out a bunch of YouTube videos with her in them. (She's too cute and super organized!!) I've become addicted to watching minimalism videos lately and just need to put everything I've learned into action. I started by evaluating all of my belongings, sorting the things I use frequently and need apart from the things I've kept around just because I had a feeling I might need them. I'll end up posting an update article later on about how minimalizing my belongings has gone, but so far I've cut my hoarded crap in half which is great. The main concept I've kept in mind when I've evaluated my stuff is what the book Spark Joy is about, does this item spark joy? Does it make me happy? Do I feel something special when I hold it? If it doesn't, I put it aside to throw away or donate. The only items I'll continue to hold onto in my hoard pile are special photos and albums that I treasure and little trinkets that mean a lot to me.
