Which Lisp? Beginner

Hi All! This likely doesn't matter much, but I'm curious on which lisp dialect would be best for somebody new to lisp? Currently I'm comfortable in C, Python, Java, SQL stuff, and web dev stuff, but I've never touched Lisp. I don't have a 'project' with Lisp yet, but my goal is to 'get the lisp mindset' of why this language is so special. 'Think like a lisper.' Open to any and all thoughts!
