Do what you're doing (5)
I believe the answer is:
solve
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">do what you're doing</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for solve that I've seen before include "Decipher" , "Explain (a mystery)" , "Find the key - work out" , "Work out answer to puzzle" , "Person living voluntarily outside their own country" .)
