- Participate in a Hackathon / Weekathon, build and launch your own product, and build up your network.
- If you have a non-tech background, write a proposal, find some friends in tech, and cooperate with them to build your own stuff.
- If you have a tech background, you can either form a team or go solo, build your own app, and release it to the market.
Read Product Books
I always recommend reading books over articles or short videos since they provide you a better big picture and foundation of product management.
Start with the starter books here: A Library of the Best Product Management Books for Product Managers
Enroll in a course
There are not many quality courses out there, the best course in the market I can only recommend is Reforge
Find APM or Product Internship Role
Find a company or a startup, especially ones with Sr. Product Managers willing to help grow aspiring PMs.
Ask your managers if they can assist you in trying out the PM role.
