Ko te mea i kaha ki te tuhi i tenei huahua ko te tuhinga . I kitea ano e ahau te tuhinga i whakaputaina i nga tau 4 kua pahemo he pai - .
Ko te ahua pai ko taua whakaaro ano - "whakatinana i te arorau pakihi i roto i te papaa raraunga".
Ehara i te mea ko ahau anake i puta mai ki te hinengaro.
Ano hoki, mo nga wa kei te heke mai, i hiahia ahau ki te pupuri, i te tuatahi, mo au ake, nga whanaketanga whakamere i puta mai i te wa o te whakatinanatanga. Otirā ki te whakaaro kua tata nei he whakatau rautaki ki te whakarereke i te hoahoanga me te whakawhiti i te arorau pakihi ki te taumata o muri. Kia kore ai e whai hua nga mea katoa kua oti nei te whakawhanake ki tetahi, kare he painga mo tetahi.
Ko nga tikanga e whakaahuatia ana ehara i te ahua o te kitenga, i te mea motuhake ranei. mohio pehea, He mea matarohia nga mea katoa, he maha nga wa kua whakatinanahia (hei tauira, i whakamahia e ahau he huarahi rite 20 tau ki muri i runga i Oracle) I whakatau noa ahau ki te kohikohi i nga mea katoa ki te waahi kotahi. Mena he pai mo tetahi. E ai ki nga mahi kua whakaatuhia, he maha nga wa ka tae mai te whakaaro kotahi ki nga tangata rereke. A he mea pai ki te pupuri i a koe hei maumahara.
Ae ra, kaore he mea i roto i tenei ao e tino tika ana, ko nga he me nga hapa ka taea. Ko nga whakahee me nga korero e tino manakohia ana, e tumanakohia ana. Tonu, kei te whakamahia tonu nga mea katoa i roto i te tino kaupapa mahi. Na, he tuhi noa te tuhinga me te whakamaarama mo te kaupapa whanui, kaore he mea ke atu. Kei te tumanako ahau he nui nga korero mo te maarama ki te pikitia whanui.
Ko te whakaaro nui ko te "wehea ka raupatu, huna me te tango"
He matarohia te whakaaro - he aronuinga motuhake mo nga ripanga, he aronuinga motuhake mo nga mahi rongoa.
Kaore e taea e te kiritaki te uru tika ki nga raraunga. Ko nga mea katoa ka taea e te kiritaki te waea ki te mahi rongoa me te tukatuka i te whakautu kua riro.
