How do I effectively communicate my desire for a promotion without coming off as pushy?

I've been in my current role for over two years and have consistently exceeded my performance targets. Recently, I've been thinking about my career trajectory and feel ready to take on more responsibilities. I want to approach my manager about a potential promotion, but I'm unsure how to bring it up without sounding entitled or pushy. I've noticed others have been promoted within the team, and I want to make sure I advocate for myself in a respectful way. What are some strategies to initiate this conversation? Should I prepare specific examples of my contributions, or would it be better to express my interest in growth first? I’d appreciate any advice or experiences you can share about how to navigate this type of discussion effectively.
