Hi merty and welcome to whiskywhiskywhisky
Each and everyone has different skills in the art of nosing and tasting. I would say my skills aren't very good compared to others, but I trained my skills with a lot of practise
Different people also pick up the same things and describe them differently..I know a person than always describe those whiskies as grassy that I describe as citrus
The first year I drank whisky I had to labels for a whisky, and they were "I like it" and "I like it a lot". But a lot of hard work and practise I now find I am getting better at it.
In Pip Hills whiskybook "Appreciating whisky" there is very good descriptions of how we taste and particular nose (--whiskies)
Our sense have the habit of excluding a constant background smell, then making us able to note the lesser things, so spending some time nosing a whisky may reveal some things to your nose.
Seeking out some "extreme" whiskies might help build up a nosing background, something very sherried (MAcallan) or very "vanilla" (bourbon cask - Glenmorangie)
