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

'planning for the best' is the definition.
I can't judge whether this definition defines the answer.

'good friends to dine ten possibly?' is the wordplay.
'good friends' becomes 'wellin' (I am not sure about this - if you are sure you should believe this answer much more).
'possibly?' indicates anagramming the letters (I've seen 'possibly' mean this).
'to'+'dine'+'ten'='todineten'
'todineten' anagrammed gives 'tentioned'.
'wellin'+'tentioned'='WELL-INTENTIONED'

Can you help me to learn more?

(Another definition for well-intentioned that I've seen is " having good thoughts".)
