"Human nature means that institutions at some point lose their sense of mission. That sense of vulnerability drives Pimco"

This quote by Bill Gross talks to the idea that all institutions, no matter how effective, are vulnerable to losing their sense of objective over time. This is because of humanity, which can cause complacency and a lack of focus on the initial goals of the organization. This sense of vulnerability is what drives Pimco, a global investment management company, to remain focused on its objective and to remain watchful in its efforts to achieve its goals. By acknowledging the potential for objective drift, Pimco has the ability to stay on track and remain effective. This quote acts as a suggestion that all institutions must remain knowledgeable about the capacity for objective drift and take actions to ensure that their objectives stay the focus of their efforts.
