I think people really resist the notion of free will being a myth because they think:
Well I try hard and I have goals, so isn't my will the driving force that creates the intention to try hard or sacrifice in hopes of reaching these goals?
I don't believe in free will but I still believe in trying hard, setting goals and getting at life.
