Do you go through life with a purpose?

For years I've felt like I've been going through life without one. I use to have goals that I felt defined who I wanted to be, but once my values changed (enlightenment from experiences and documentaries) and didn't agree with them I felt I lost my way. Through reflection and insights from others I've realized this is part of growing up and developing character, but I must say that doing an about face away from where I was headed is no easy task. How do you guys handle the day to day hustle? Do you live in the moment and embrace it or do you wake up everyday with a set of sub goals in mind that leads to something bigger...or do you do something completely different?
