I believe the answer is:

egg

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

'urge' is the definition.
(as in egging someone on)

'for one to stick with golf' is the wordplay.
I cannot really understand how this works, but
'golf' could be 'g' (phonetic alphabet: alpha, bravo, charlie etc.) and 'g' is located in the answer.
'for one' could be 'eg' (both can mean 'for example') and 'eg' is found within the answer.
No letters remain.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for egg that I've seen before include "Reproductive part" , "On the face, it's embarrassing" , "explosive" , "Food from a hen" , "brick is a good one" .)
