A young swimmer initially learns the technique to swim, only later, he swims better. 
This is an example of just about anything.

You can understand how to get into the flow to focus better and win the race, only later, with practice and patience.

You can't expect to increase your focus in a snap of your fingers. Whatever you want to do, you have to learn first.

Learn to use the tools. Learn to understand some topics, perhaps by reading. Then you have to absorb everything you have learned and, only with consistency and repetition can you increase your level of concentration and be faster and faster. Keep that in mind.
