I don't believe free will actually exists for most. Were all so influenced, programmed, and most of us have entity attachments controlling over our thoughts/actions. How can you have free will when we've all been treated like toys since being born into this world.
A person wanting to buy a diet coke, might think they have free will to buy it or not to buy it. But the programming of coke commercials are deep. They might not really want a coke, but they feel like they need one. Where's the free will in that situation?
You have to bypass the mind-control, programming, influences, and get rid of the entity attachments to find free will.
