Tony's motto is "you've never played as consistently," and it is entirely accurate. The daily challenge routine is very addictive, challenging, and motivating. The lessons are unique: Tony doesn't teach you how to play a specific play song or style. He teaches you all aspects of playing the guitar, so you can develop your own style and create your own music in time. I love the constant exposure to new styles and techniques: the lessons vary between chords, flatpicking, fingerstyle, fretboard navigation, improvisation, etc. Yet there is a system, so it's not chaotic, and the lessons build upon each other. It also helps that Tony has a great teaching style and personality. The lessons are never cringy or irritating, and the explanations are always clear and to the point.
