'adjusting' is the definition.
(zeroing is a kind of adjusting)

'nothing upsetting or close to terrible in life' is the wordplay.
'nothing' becomes 'z'.
'upsetting' says the letters should be written backwards.
'close to' says to take the final letters (the close/ending of).
'in life' becomes 'ing' (I can't justify this - if you can you should believe this answer much more).
The final letter of 'terrible' is 'e'.
'or'+'e'='ore'
'ore' backwards is 'ero'.
'z'+'ero'+'ing'='ZEROING'

'to' acts as a link.
