Speaking only from personal experience. Take what you will.
Sometimes, we overthink stuff. It is okay to be however you approach things. You don't need to be exactly (skilled/good/whatever) like the people you see. I found that, if I stopped thinking too much, and stopped worrying about a specific version of me I have in mind, I just _be_ and end up doing something spontaneous, and leads me to a state I did not originally plan for.
Professionally, I studied computers, and I worked to find my way within the field. Tries being a consultant, software developer, people manager etc to realise that I didn't like any of them, and then stuck to caring for systems and how they work which has been the fascinating part all along. Now, I work as an SRE. Happy to come to work, and inching forward on being a good SRE everyday. I do have a big imposter thought when I listen to talks/ works of other SREs, but this is me. I know and can do things they probably can't.
Hobbies wise, I think the best ones are organic, and happen by a bit of chance + social effect. I ended up playing with a few wood working tools at a garage of my friends' when I was a teenager, and it was always a good memory. When I was away from home, living alone in the US, and had lot of time in my hand after work, I found a local community wood workshop and went there for a woodworking class. It gave me a good time, and I ended up visiting more and more often. I have now been woodworking for the last 12 years, and it is one of those hobbies that make me forget about the rest of the world, when I am focussing and working on a project. I religiously visit my woodshed for 5 hours every Saturday, and it is my time where I can build something tangible and feel the sense of accomplishment without caveats.
Just sharing my experience in case it helps you.
