Jonas Salk Quote

The evolvers are people who cause things to change. The maintainers of the status quo do everything to keep things from changing. And, there I see differences of perception. Differences in vision. Differences in interpretation, and differences in temperament, in personality. The number of evolvers are much fewer than the maintainers of the status quo. And amongst the evolvers, there are some who are initiators, some who go along with what other people recognize to be new or different.
