'advice about moving on' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'silly to grieve over time?' is the wordplay.
'silly' is an anagram indicator.
'over' indicates putting letters inside.
'time?' becomes 't' (abbreviation).
'to'+'grieve'='togrieve'
'togrieve' with letters rearranged gives 'geoverit'.
'geoverit' placed around 't' is 'GET OVER IT'.

'here's' acts as a link.
