When the rubber hits the road, the reality is less utopian. Human competition is the most brutal. An inconvenient truth is still a truth. Consider yourself warned. This is my last response to this thread. Good luck!
P.S.1
要特別三思的人, 是那些using other people's money的.
用自己的錢(or bear a loan oneself), 和時間, 做甚麼都只是對自己負責.
但是如果是用別人(e.g. 父母)的錢的話, the story is completely different.
