'travel widely' is the definition.
(I've seen this before)

'good to see have confidence to go off' is the wordplay.
'good' becomes 'g' (abbreviation).
'to see' becomes 'lo' (archaic word meaning 'look!').
'have confidence' becomes 'bet' (I can't explain this - if you can you should give a lot more credence to this answer).
'to go off' becomes 'rot' (I've seen this before).
'g'+'lo'+'bet'+'rot'='GLOBETROT'

'and' acts as a link.

Can you help me to learn more?

(Other definitions for globetrot that I've seen before include "travel extensively" , "travel widely" .)
