What would be the best roadmap to become a successful PMM?

There’s probably a thousand different combinations of answers to this question, depending on who you ask. I’ve seen incredibly successful PMMs come from all sorts of backgrounds - everything from engineering, to education, to real-estate backgrounds, and everything in between. However, I think there are 3 common skills that I’ve seen across the most successful PMMs I know: 

1. Empathy and understanding of your customer base and what they want.
2. Excitement and a deep knowledge of your product and the space you play in.
3. The ability to tell a compelling story to not only your market, but also across your many different internal stakeholders. 

If you can demonstrate your expertise in any of these areas based on your previous experience, that will help open the door to PMM interviews, even if you don't have direct PMM experience in the past . Also worth noting is make those skills apparent on your resume, LI, etc...and be clear about why you're looking to shift your career and how your previous experience will benefit the team. 

It’s rare to have mastered all 3 of the above skills, but in my opinion, this should be the north star(s) for every successful PMM. And lucky for us, there are plenty of roads to actually get there. 

Nobody is ever fully prepared to take that next leap. The fact that you're here on Sharebird learning is a good first step. In regards to building courage, the worst thing that happens is you apply and don't hear back from the employeer, there's only opportunity. If you've managed 4.5k employees you probably have some relevant experience that will get you a call back.
