Isifundo apha sesokuba amava amnandi akhokelela kukuzithemba, kwaye ukuzithemba kukhokelela kwimpumelelo. Ukubanjwa ngesandlaisarha ezijikelezayovula uluhlu olubanzi lwamathuba okuphucula ikhaya. Yiyo loo nto besisixhobo esisebenzayo kurhwebo. Iqhinga kukufika kwisigqibo esifanelekileyo malunga nokukhetha isixhobo njengomninimzi. Ndiyakholwa ukuba esinye sezizathu ezibambe ngesandla isarha setyhula azisoloko zithandwa kakuhle kwizangqa zokuzenzela kukuba abaninimzi abaninzi bakhetha iisarha ezitshiphu, ezinengxaki. Ukuba ucinga ukuba ufuna isarha esetyhula, kufuneka ilungile. Kwaye oku kuthetha okungaphezulu nje komzekelo wezoqoqosho.

Kungakhathaliseki ukuba uyilo lwesarha oyikhethayo, ixabiso lesixhobo lilibalekile ixesha elide emva kokuba umgangatho uqhubeka ukonwabela. Nxiba iiglasi zokhuseleko kunye nokukhusela ukuva xa usebenzisa isarha, thatha ixesha lakho ngokusikwa nganye kwaye ube nomnye umntu obambe i-workpiece yakho kwinto eqinileyo ngelixa ufumana isakhono ngokusikeka kwakho kokuqala. Leyo yindlela uNorm ayithathayo kwaye ngoku unophahla olutsha olomeleleyo kunye nokuzithemba okukhulu.
