Amathambo ayo aguquguqukayo ukuze ithathe indawo encomekayo. Imilenze yayo ithe tyaba ukuze ikwazi ukudada kakuhle kwaye imile okokugqibela. Iinzipho ziyafana neekati, eziququzelela eminye imisebenzi enjengokuzilungisa nokubamba kakuhle ixhoba lazo. Umsila unemisipha kwaye Ngokusisiseko bayayidinga ukuze balungelelanise ulwalathiso ababhukuda ngalo. Ikwabanceda ukuba balondoloze ulungelelwano lwabo kakuhle.
Abantu abadala banamazinyo angama-32 anemicaba ecekeceke yaza yajikeleza imisonto elungiselelwe ukugaya kunokuba isikwe.
