Build in public - authenticity beats expertise

You are the best you out there. So for example... let's say you are a 21-year-old PM, fresh out of school, first year... you just talk about your journey, talk about what you're doing, talk about what you're learning.

Don't wait to create amazing things. Often just the act of putting yourself out there can just spur amazing things in itself.

Show up with curiosity and a passionate engagement for what you do, and people won't notice your wrinkles as much as they'll notice your energy.

Share your knowledge one way or the other. And as you're doing it, you're going to learn a lot more. If you're thinking of a newsletter or something similar, start teaching and sharing what you know and what you're observing. This could be a newsletter, this could be a YouTube video, this could be going to meetup.
