How to manage my time in a more appropriate and usable way.

Still getting confused about what am I doing right now. Sometimes I feel as if I am the only one who is laying on the bed without any reasons and ideas about what shall I do to proceed my plans and it had become my habit of being so clueless and effortless. I know what I want to do but I just can’t, being so helpless of myself. I just think too much and Waste at my max. Whenever I tried to free up my mind and start with a new episode I get stuck up by my own way and you know what I am still thinking if this what am I writing is taking my time or not. I must say, anything I do besides my studies makes me feel as if I am still wasting time. Exams are approaching near and there’s a lot to study and memorise. Even though IAM on a platform where I didn’t even started and wishing for the overview and revise which is not possible at all. Basically often the reason behind all is that I am too lazy of even doing the thing what am I thinking. I just lay in the bed working with the mobile phone and still wondering why am I doing this besides having my time in a more beautiful way as I want. All I know is that I am from those who fall prey to self-deception. But I made my promises now to start using my time in a best possible way from tomorrow itself and to manage it in a more appropriate and usable way besides being so reluctance and ignorance with full devotee and a clear plan for it.
