So in our field of work we 'specialise' or become dedicated but my suggested benefit is to help freshen others when you see them trying to punch out of the same paperbags or hitting the punchbag (what people have grown into doing for a long time usually as a reflection of what life is not giving them).
Also to confirm others - "you're doing great"
Their cause (our cause as humanity) is often honourable or in good will but externally others are naturally needed to help others come around from another angle or radius, and even refresh their perspective *without* going against them so much, more a curving (unless someone like me doesn't mind you give them the shit straight up and loves you for it!)...

TLDR Others help give wholesome perspective...

Extra...
...On our own we are warriors - and that can work also though often is a bit 1-dimensional and anyway we are informally working together organised or not - I prefer more warm contact of approach - get in contact :)
