A few simple exercises are helpful in promoting concentration, and you can also use unusual situations to learn how to focus. Often in an office there is soft music playing in the background and colleagues are talking to each other. You can use this background noise for an exercise by waiting for a certain word and counting how often it has been used. Conjunctions such as “and” or “or” are particularly suitable here, but also pronouns such as “I” and “you” or “you”. The quieter such “overheard” conversations are, the more you have to concentrate and the more effective this exercise is.
