Leadership, and why we heck care?

At the workplace, we are asked to groom our leadership and take ownership or be proactive. Everyone is asked to show progressiveness. Sometimes, i wonder how about someone just want to be himself, working at his own pace, is he still deserve a place at working environment? Can he openly say this out, sure he can, but doing so, he deemed to jeopardize his own career. Yes, it's me. I don't mean i don't like my job, I just hate the feeling of stretching. Life is a marathon, and not a sprint. Just do good work, enjoy yourself, however said, at times I still need to pretend I'm passionate. As I still wish to rise through the rank in the organization, therefore follow the mainstream is important. I just don't know if i'm alone.
