time manage'' stuff is now obsolete 
the new approach is to meditate, 

effectiveness will become spontaneous, effortless
life will be lived with a higher science, better sense

nature cooperation will be maximum, 
as if god does your things

in effect you are delegating a lot to god, 
he becomes your most trusted subordinate

yatheenaam brahma bhavathi sarathi
god is the servant of his bhaktha

he is dasaanudaasa
so better update your understanding
