気が散って大事なことに集中できずないというのは、気が散りたいという内からの衝動があるからだ。この衝動を抑え込むのでなく、受け入れつつ、やるべきことを始めることがこつだ。

 watch out for the inner urge toward distraction, and when it arises, don’t beat yourself up, or try to squelch it. Just sit with it, breathe, and let it dissipate. Remember, too, that you don’t need to “feel motivated” in order to do important work. Instead, let yourself feel like you’d rather be doing something else, and at the same time, do the work

make time in your schedule for frequent journaling, ... to ensure you’re addressing those big questions.  you’ll find .. that the urge to distract yourself in order to avoid them will fade accordingly... also, that external temptations and interruptions bother you less. Distraction is an inside job... means there’s no need to eliminate every external annoyance before you can start to focus on what matters most.
