There is a component in contentment that I think is lacking in complacency...that of general happiness. So to me, they are not the same.

As someone who has a growth mindset I can assure you that in corporations like Microsoft or Intel (I worked at the latter), one's own personal growth is not only fostered, but highly encouraged.

Corporate life ain't for everyone and I get that. As a 56 year-old being squeezed out of the marketplace due to ageism, some of us aren't just after the highest pay or the most prestige at our jobs.
