The poly-sci's get their rude awakenings when they graduate, the engineers when they turn 40
An engineer needs to spend his 30's preparing to start his own business
"An engineer needs to spend his 30's preparing to start his own business"
I agree. Like many fields, an engineer in his 40's cannot compete with the younger, sharper minds of engineers in their 20's. That doesn't mean they are unemployable, it means that they take their experience and perspective and evolve.....starting your own business is definitely one of those options.
Of course, the days of lifetime employment are over for everyone, not just engineers, one should be prepared for change no matter what your age.
Those who came to this realization a little late are quite apparent on these threads.
