Let me share with you how I started.
Just to give you an idea, I had no clue what an API was, but I understood that this thing called Agile was more about people and I liked that. This gave me a lot of energy to learn new technical things and to channel my passion towards outcomes.
But, it was HARD at the beginning.
On the way I discovered new topics I had no clue about them and what puzzled me most was how was I supposed to learn all of these topics, when I actually needed them all to provide quality Outcomes? The answer was: read a lot and baby steps.
Read a lot does not mean read anything. This is one of the most important things I learned from my Scrum Alliance Trainer - it is highly important to read high quality materials (articles, webinars, interviews). What you learn from others is what you will share with your teams/organizations. If garbage in - garbage out. How do you know if one article/webinar/podcast is valuable? - well, you just feel it.
When you want to start on your Agile Journey I suggest you get a mentor to guide you or simply find people in the world who can inspire you.
Here is a list of people who inspired me, that you can use as a start for your learning journey: Richard Kas
