Today, listening to some video, I made a realization that "disappointed" needs the preposition "in" when talking about people, like "I'm disappointed in you," but "with" when talking about things. e.g. I am disappointed with my results. After checking the dictionary, it seems it's possible for things to use at/with/about as well. Is it so ,right?

Ok, I was writing something yesterday, and grammar correction corrected me. It was putting the article "a" before "strength." For me, "strength" is an uncountable noun, so why does it need "a" before it? I assume it is the concept when nouns are both countable and uncountable. I notice I always make mistakes with them . How can we identify when they are countable or uncountable? (I mean these nouns, which are both)?
