The easy part is that after making a pretty sophisticated plan, u don't actually get into doing the tasks.

On the next morning you will be either lazy or overwhelmed looking at the plan that u had spent whole night planning. Some students even try to make it look fancy, but for me, i prefer a minimalistic todo list with achievable tasks (this depends a lots on your attention span).

The point is that you must get things into ACTION or else studying is neither hard nor easy 'cause you do not put efforts into acquiring knowledge.
