I have always been curious, which is a great trait for science. Taking things apart and putting them back together, trying to figure out what types of birds are coming to our feeder, or trying to blow up the sun by reflecting it's light back at it with pot lids (I was 6, it seemed like a strong hypothesis at the time).
It is important to stay curious, some things I like exploring are:
Ornithology (birds)
coding and circuitry
Literature (lots of fantasy /sci-fi, ask me for recommendations!)
woodworking
In any of these things, or anything in life, there is learning and problem solving. And Science gives us the framework to learn, explore and grow. It is not just a body of knowledge, but a way of thinking!
