Utilitarianism as a tool

In its standard formulation, utilitarianism is big burden on one's life. It demands to make all decisions on rational and impartial basis. Utilitarian ideal is human-robot that doesn't act accordingly to human nature or emotions, but based on cold, precise calculation of utility.

It is main reason, why people reject utilitarianism. They are not willing to make huge sacrifices, they are not comfortable with pressure it entails. It is understandable and still those people can benefit from utilitarianism. How? Metaphysics

They should treat utilitarianism as a tool. Easily and directly applicable, to all daily dilemmas and moral conundrums. So rather than use it actively, to all decisions they make, they should use it passively – only when it is needed. It probably won’t be as beneficial to society as active approach, but still much better than rejecting it whatsoever.
