Hi Pia. You're right when you say it's about a person.
This sentence is quite weird and difficult to translate. If you have a look in a dictionary, you'll find your translation. But here I agree with Minny. The meaning is something like 'you're able to do something" but on the other hand yours "you're good enough" could work to. I'd suggest, that one of the sentences should be written
in the comment field.
Thanks for your input. I hadn't thought to much about it.
