Time management!!!

One thing you can't recycle is "Wasted time"... so here comes the BIG question, how to manage time?
Usually when i am in campus or at home, i spent maximum time in doing useless things and later i complains that i don't get time for doing creative things or to do something related to study. generally people also have the same complain which i had earlier.
there are many factors responsible for this like not setting the priorities to your work, postponing important tasks because of doing something which your mood says & is more enjoyable or that you’re more comfortable doing, poor organizational skills,
not using your free time wisely...
one day i sat and analyzed what i did and where i spent maximum time and came up with some new & useful ideas. I don't believe in making a chart and then working according to that but still a layout is necessary to manage time.

when i was in school one of my teacher gave me "P-3 tips".

1. Planning
2. Preparation
3. Presentation

before i never paid attention but now i follow it and it really helped me a lot. Now i have a schedule in mind which generally i follow and work accordingly which not only solved my time management problem but also keep me free from tension and stress.
