I think of everyone as engineers of love. Therefore the best engineers of love are the best lovers. Some call it pleasure, love, happiness, etc. To me it all leads to feeling good. Being happy.
Everything anyone or any creature does is to engineer that good feeling. Therefore, the more one knows about engineering, which includes math, logic, reasoning, the scientific method, project management, etc., the more capable they are of engineering love.
Some say function has no purpose. But I think all function leads to feeling good. The more masterful one is at the science of mechanism, the more capable they are at engineering love.
Knowledge is power, some say.
