Is it normal to give up your foolosophy?

You know what I mean. I observed through song and religious talk by a singer (Jamiroquai) and a speaker (Osho) that a lot of people will die believing in their foolosophy, but do many people give it up? I wonder! Love foolosophy (Jamiroquai), I can relate to, because I have a love philosophy, I'm not sure if it makes me a fool, it's probably not actually the pursuit of wisdom, but a modern philosophy, as taught in the novel 'On Love', based on a tradition of philosophy. My love philosophy is love at first sight, making love, getting the correct phone number, finding clues as to what a woman wants without thinking that asking questions about them is that simple as to know what she wants after that, that she could be lying, and to not be cynical with a woman about love (he means sex), I'm not about to give that up, but I'm giving up my 'bullshit' foolosophy because it doesn't work, it causes people to say "bullshit" with everything I say, I got appalled at that for the last time, and decided not to ever be accused of bullshit again, is that normal?
