The practical, everyday application of philosophical ideas, moving beyond theory to integrate wisdom into actions, values, and decisions. Honestly, this may be pragmatism, which is yet another philosophy. And if we want the philosophy that suits human nature the most, it may be hedonism. Some philosophies like nihilism are only theoretical.
Philosophies help you with thinking skills, so even with a non-applicable philosophy, your brain power is still increased! So philosophy does help with living (and other knowledge can help with life too.)
