as many people i talk to, which are not many, but no one seem to love his/her corporate job ... why?

because by design, a corporate is big, so many people, so many agendas and everyone above, below and on the side is ambitious, & potty trained; i mean politically trained, driving you nuts, unless you are better than them ... throwing shit back at them... which builds up stress and productivity goes down ... so, mostly you are thinking about politics and survival.

solution: keep organization small, one person responsible, simple agenda; people stay in it or leave ... some may call it VIP style dictatorship .. so be it, at least it will keep you honest and happy ..!
