Before I tell you what 30 Days to Diamond is about, let me tell you what it isn't. This book is not the next three-dollar booklet promising you all the "tips and tricks" nobody else knows. Any book that makes such a claim is ridiculous, misleading, and a waste of time. 30 Days to Diamond is 143 minutes worth of specialized teaching, produced by a Master Tier player on both EUW and EUNE servers. It teaches all technical, strategic, and psychological aspects of the game, from A to Z, in a very unique and effective manner.
If there's anything I've learned after mentoring over 60 silver and bronze players, it's that anyone, and I mean anyone, has the potential to become a Diamond level player within a very short time, even if still new to League.
In spite of all the information available online, the majority of League's community still struggle to achieve their goals in Ranked. Nowadays, there are so many Twitch streams, YouTube channels, and websites dedicated to teaching the game, and yet the results are just not there for the majority. Improving from Silver to Gold is nice, but this is so much less than what progress should look like for most. Being a teacher in real life, the question I got absorbed in was: What prevents people from mastering the game to the level they want, despite them having access to all the information they need? We are talking about hundreds of thousands of players that play ranked. That's a lot of people. Why is it that so many folks may spend weeks, and even months, watching Challenger streams, play League for 5+ hours a day, and still not improve at the rate they could? This inefficiency is not due to the people playing the game, or the information they learn from. It all has to do with how effective learning takes place. A person's ability to learn from a piece of information is enhanced only to the degree to which they can relate to it at that specific moment.
