"Live in a blur" is a metaphor that means he never saw things "clearly" or for what they were. His perception and experience of life was "blurred", obscured, or not clear until now. Ex: Sometimes, I feel like I'm living in a blur, and I just keep pushing myself to keep going. Ex: I used to feel like I was living in a blur, and then I realized what my passion is. Ex: It's pretty blurry without my glasses.
