The person who will make the greatest contribution to a company is the mature person-and you cannot have maturity if you have no life or interest outside the job.
Peter DruckerThe next thing to be said about what long-range planning is not, is that it does not deal with future decisions. It deals with the futurity of present decisions. Decisions exist only in the present. The question that faces the long-range planner is not what we should do tomorrow.
Peter DruckerThe knowledge we now consider knowledge proves itself in action. What we now mean by knowledge is information effective in action, information focused on results. Results are outside the person, in society and economy, or in the advancement of knowledge itself. To accomplish anything this knowledge has to be highly specialized.
