While I wouldn't generally call my buddy max succinct, he sure is pithy. :wink:
Pithy? Pithy??!!! Who you callin 'pithy', thithter?? Oh wait . . . hey, that's not so bad. I especially like that 'forceful' and 'full of vigor' part.
pith⋅y  [pith-ee] –adjective, pith⋅i⋅er, pith⋅i⋅est.
1. brief, forceful, and meaningful in expression; full of vigor, substance, or meaning; terse; forcible: a pithy observation.
2. of, like, or abounding in pith.
Why yes, I would say I am 'abounding in pith'. Would anyone like to relieve me?
