Not to cool your enthusiasm, but there are a number of discussions on the forum about people over-zealously pursuing professional status (e.g.: dive master or instructor) way too early in the scuba hobby. From what people have to say, it is often far from lucrative, the prime locations often highly competitive, and the realities of teaching, working for a dive shop or boat, etc..., often entail a life style far different from what the aspiring pro hoped for.
It's also been put forward that the requirements to become a DM or Instructor are rather minimal, and you'll see the phrase 'zero to hero' used at times.
I think some people think to pursue professional status thinking that's how you get to be a really good diver. After all, if you want to really master something, wouldn't becoming a pro be the way to go?
If you don't have 25 dives in yet, and for that matter a good deal more, we're getting ahead of ourselves, but I'll say that there are a number of self-improvement paths to build skill, knowledge & experience without getting DM or Instructor credentials. You'll see people talk about GUE Fundamentals later, but just diving a lot with good mentors can do a lot.
If you do PADI Deep Diver, be mindful that basic course is also rather minimalist. You can learn a lot about deep diving on this forum, and you should to supplement what you'll learn in the course. Discussion about nitrogen narcosis at depth, gas reserves, thinking about how much has it'd take you & a buddy to do a proper ascent and safety stop from depth in an anxious state, that sort of thing.
On the other hand, seriously consider aiming for Rescue Diver once you're comfortable with the basic skills in the water. It can do a lot for your mindfulness and maturing as a diver. It is not just a 'volunteer scuba lifeguard' course.
