I strongly believe that when you hit a certain age, you suddenly develop opinions on things you never had opinions on before. For me that age is 26. Here I am, basically the same human I was 365 days ago, but with some strong opinions. Here’s what they are.
I’m a cat person. Full stop. Sorry dogs, you’re cute and all, but it’s the cat life for me. Just look at that photo of Gallifrey a year ago. Adorbs. For a while I would appease people by saying we had only cats for convenience’s sake. I’d assure them that I was both a cat, and a dog person. A few years ago we almost purchased a corgi puppy. That Kayla didn’t know what she was thinking. This Kayla? Oh I’m sure. Cats all the way baby.
Do whatever you want as long as it doesn’t bother anyone else. Specifically enjoy whatever hobby you want. I recently started playing Dungeons and Dragons. Two years ago I would have hesitated and really thought about if I wanted that fact on the interwebs. Now? Screw it. It’s a whole lot of fun, gets me and Alex out of the house, and I’m not afraid who knows it. When we’re younger we’re always trying so hard to keep up with appearances. I’d play down the things I love (board games, houseplants, etc.) and play up the things I knew other people like. Just plain silly.
I’ve also firmly decided I’m a plant lady. It’s taken me quite a while to get to this place. Unfortunately a lot of dead succulents along the way, but here I am. There are twenty-five glorious green creatures in our house thus far and as long as Alex is cool with it, I’ll keep adding more. 
When Alex met me six years ago I think it’s safe to say I was a materialistic, shop-o-holic mess. Now? It’s more about the moments than the things. If I suddenly had to uproot, downsize, and travel the country in a tiny house I wouldn’t hesitate to grab my cats, a few plants, our board games, and be on my merry way. Over the past few years I’ve abandoned my attachment to stuff and become more attached to the adventures instead.
I’m sure over time I’ll make even more adult decisions, maybe change a few along the way, and stop being phased by what everyone else is doing. Sure being an adult comes with joint pain for no apparent reason, but it also comes with self-assurance. And I can dig that.
