Find the eternal you that is not this physical body, that is not these thoughts, that is not these emotions, that is not these circumstances.
When you find it, skepticism is natural. It may seem like an illusion. The more you explore and realize this eternal you, the more you realize this physical body and this physical world was the illusion all along.
Once this is realized and you see the world for what it really is, you can start to experience this life the way the eternal you intended to.
