Nini said something smart today. (She is smart everyday.. but today.. especially)
The reason why some people are very gung ho and are able to deal with ambiguity, and not think too much, is because they have the " if somebody else can do it, it is possible, so i can too", attitude.
Although, I feel that there is this variable left out of the equation. Some people have higher tolerance for "masa susah", and some less. So, might not work for everyone.
But generally, think the above saying can be applied. It is just that we need to sometimes think of the worst case. In papa's words: "Yang penting hati bulat, everything else is secondary"
An uncle once said to me," You nak buat business?, kalau sanggup duduk tepi jalan merempat, then you bukak business, because that is the worst thing, bankruptcy"
Quite true. But a bit too drama for my liking. :P.
