A pilot can fly a plane, and understand its broad (aero)dynamics. But one cannot expect her/him to assemble a plane from scratch.
The operations head of a dairy company can manage supply chain and milk delivery to customers perfectly. But expecting her/him to understand the nitty-gritties of bovine health and feedstock is silly.
An expert fashion designer might have the best eye for haute couture. But putting her/him in charge of a fashion company – to deal with all the finances, HR, operations and technology – would be incongruous.
In life, mutual interdependence is inevitable. Not one single thing in this world happens independent of anything else. We wouldn’t even be able to breathe, if it weren’t for the trees around us.
Likewise, it is impossible for one person to know everything. But we are often still too scared to ask others for help. If we are perceived to have low IQ or poor calibre – but that is the perceiver’s problem! And this is rarely the case though – because everyone loves to give advice and most people love to blah blah blah as they love the sound of their own voice.
It is better to ask and find out, than stay silent and never know, or worse, get an inferiority complex, when there should be none.
