First, philosophy means "the love of wisdom," so other than that, it needs no practical use. But as a matter of practicality, philosophy affords one a sense of history and perspective with which to better judge the world and one's place in it. Thus through philosophy we learn what life values and behaviors enable us to enjoy life and live satisfying and fulfilling lives.

Having said this, I suspect you are not open to any positive remarks about philosophy, or you would not ask the question.
