To become more successful with a thing than we already are requires us to learn a new and better way. We then apply what we are learning in the process to gain to a higher level of mastery. Without concentration, the efforts to learn will falter.
Concentration is critical to the learning process. The mind must be opened to focus on what matters most in acquiring the knowledge and the actions to demonstrate improvement. To focus on everything, we progress with nothing.
If the focus were to save our life from an imminent threat, the concentration level would be very strong. If the focus were to be less intense, so will the outcome of that effort. From focus comes growth, set the focus of concentration on the element you will need to learn the most from.
Have a practice of learning where you will concentrate with diligence and you will succeed to your full potential. Half-ass this practice and you will largely remain the same, only hoping to have learned. Self-initiate learning, who else would set the best course for you?
