Simple=Difficult

Hi friends,

Few days ago I was asking myself that why is living so simple routine so difficult?

For a student like me, I made a sample routine:
Get up at 7 a.m.
Get ready till 9 a.m.
Studies till 11:30 a.m.
lunch break 11:30 a.m. to 1:30 p.m.
Studies 1:30 p.m. to 4:30 p.m.
Then snacks and fun!! till 11 p.m. Maybe I can even study for one more hour if its heavy load.

This is so simple a routine! Gives ample time for eating, studying, sleeping as well as recreation!
But an unwritten law says most simple thing is most difficult to do.. You just cant simply do the most simple thing..
Why?

One more "simple" thing to do is living present moment fully. Seemingly so simple. In fact thats all is in our hands. But what we do is to waste present moment in daydreaming and consequently using our life in very inefficient way. Though we all know it well, we just cant avoid idling away like that.

Simple=Difficult?
Isn't it true?
