Be careful
You don't usually use any other negative word such as ‘not’ after nothing. Don't say, for example, ‘Nothing didn’t happen'. You say ‘Nothing happened’. Similarly, don't use ‘nothing’ as the object of a sentence which already has a negative word in it. Don't say, for example, ‘I couldn’t hear nothing'. Say ‘I couldn’t hear anything.'

He never seemed to do anything at all.
‘nothing but’
