I believe the answer is:

megastar

I'm a little stuck... Click here to teach me more about this clue!

'big achiever' is the definition.
I know nothing about this answer so I can't judge whether this works.

'maiden say as sailor' is the wordplay.
'maiden' becomes 'm' (cricket abbreviation).
'say' becomes 'eg' (both can mean for example).
'sailor' becomes 'tar' (tar can mean a sailor).
'm'+'eg'+'as'+'tar'='MEGASTAR'

Can you help me to learn more?

(Other definitions for megastar that I've seen before include "A-list celeb" , "major celeb" , "Big personality" , "Dazzlingly successful person" , "Great Sam (anag)" .)

I've seen this clue in The Times.
