Sigh. No one but you, or perhaps some faculty who know you well, can really define how "good" you are as a scientist. On the one one hand, passion for facts, and keeping general knowledge at your fingertips is a worthy state to be in. That's one thing I'm known for. On the other hand, facts are easily Googleable on anyone's smartphone, so my claim to fame is almost superfluous.
There's also a dedication to the scientific method. You have to not want to do or say anything, until you've checked and re-checked it for bias or error. That'[s something that comes from being a scientist. Still, you meet people in academia and industry who are often very dogmatic.
There's attention to detail, focusing at the work at hand, avoiding distractions and always working to improve: your knowledge, your memory, your understand of the entire process. Maybe that's being a scientist. Maybe that's being a grownup. I don't know.
But like I said, you encounter people who run the gamut of low to high ability in academia and industry.
