impresario

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

'he'll initiate a performance' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'everyman's wanting praise or otherwise' is the wordplay.
'everyman's' becomes 'I'm' (where the crossword setter is 'Everyman').
'wanting' says to put letters next to each other.
'otherwise' is an anagram indicator.
'praise'+'or'='praiseor'
'praiseor' anagrammed gives 'presario'.
'im'+'presario'='IMPRESARIO'
