Boring piece I hone endlessly following morning drive (8)
I believe the answer is:
ambition
'drive' is the definition.
(ambition is a kind of drive)
'boring piece i hone endlessly following morning' is the wordplay.
'boring piece' becomes 'bit' (I've seen this in another clue).
'endlessly' says to take the centre (the ends of the words are removed).
'following' says to put letters next to each other.
'morning' becomes 'am' (as in 12:00 AM).
The middle of 'hone' is 'on'.
'bit'+'i'+'on'='bition'
'bition' after 'am' is 'AMBITION'.
(Other definitions for ambition that I've seen before include "Aspiration - goal" , "Strong desire to achieve, fame or fortune" , "Desire to succeed in life" , "wanting to succeed" , "Target" .)
