So, This is a question I've spent the last 5 or so years asking myself. Is Marriage worth it?
The short and long of it is that its not that simple. If the barometer in your life feels like you need to focus on doing you, and marriage seems like an unnecessary obligation, then do you and don't worry about it. Who you are in 5 years, 10 or 15 is not the same person you will be today, or were yesterday. A thousand things will change your mind going forward, but Marriage itself probably shouldn't be one of them.
Aiming for marriage while you aren't dating and very much single is a little like putting the cart before the horse. In same way, I would suggest keeping your ideas and timelines about marriage pretty close to the vest until you're pretty confident you're not going to scare someone off.
Marriage is like the Penultimate of best friendships. There's only so many people you can know and see, having to choose someone and be chosen is overwhelming. So take it slow, small, and one step at a time.
Sometimes the steps you take are steps to get ready before you ever meet someone. Its accomplishing your personal goals, developing good habits, setting yourself up for success, and developing good boundaries with the friends you do make. All these things are super helpful when you meet someone you want to spend more time with.
But the biggest thing if you are going into the great big vast ocean of open market dating, marriage is a companionship. Its not a race. Its not a trophy that says, "someone actually likes me! I finally fit in!" Marriage isn't an accessory or an obligation. It is a partnership. Its the split screen Co-op version of life. Only its not just the screen, you get to/have to share pretty much everything. (Except toothbrushes, don't ever do that you heathens)
If that is what you want, I would say make room for it in your long term goals. If or when you meet someone you like having around and sharing stuff with, you might find that it grows into a priority. Which frankly seems like the healthiest way to go about life.
You seem alright, I would keep doing what you're doing and don't overthink it too much.
