Now duly supposing you are not ironic (all ages and paths come here):
You call people "brother"; "brother" means "supportive" (and is used for "openness", "closeness"); if you want to be close and supporting to people, if you want to be an asset (not a liability), you will have to cultivate yourself, to get the wisdom required. Erudition is not yet wisdom, but coupled with the good intention to learn the important things it surely helps.
That was delightful.
