Cos when you are young and self-righteous (most youngsters tend to be in this category) with no other commitments, you feel you can move freely like a fish in the ocean. Once your are bound by chains of life such as age, personal commitments, you will think twice before moving. When I was much younger, whoever piss me off, even the slightest thing in office, I will think of quitting to get into another 'better' company. Now, come to think of it, I realize how many risks I have taken before. Luckily, I am not jobless now as I know better to secure a job first before quitting, all thanks to the reckless, daring me in the past. Been through it and done it. No joke.
