...the best possible way to prepare for tomorrow is to concentrate with all your intelligence, all your enthusiasm, on doing today's work superbly today. That is the only possible way you can prepare for the future.
Dale CarnegieLooking at the other person's point of view and arousing in him an eager want for something is not to be construed as manipulating that person so that he will do something that is only for your benefit and his detriment. Each party should gain from the negotiation.
