hi
dont know exactly what you're looking for ..
but if you suffer from 'lack of attention'
i'd suggest some regular meditation, tai-chi, martial art or yoga, whatever suits you best .. you can learn a lot of useful skills form one of those, improve your attention and transfer those skills to your job ..
[hey .. books are good if you want to learn maths ..]
