I have problem on time management and also I waste time a lot. please help me not to do again.?

try to plan your time, make a to do list, be focused, set a goal what you want to manage in one day, make priorities, set alarms,

good luck

Well for starters, you should probably get off Yahoo! Answers.
You could try to make a list of things you would like to do and estimate how much time you will need to complete the task. Challenge yourself to meet your goals. When you’ve finished, see if you were able to do it in the time you estimated, if not, figure out what you could have done to get the job done on time. Treat it like a game of Beat the Clock.

Sit down before you have to start your stuff that needs focus and time. Think about how long it will take you to do those activities and say “Okay, I need to spend ___ time doing this” and after watching T.V. or whatever, say, “okay I only have ____ hours left of free time, so I need to do that activity.”

Or, as soon as possible, or before you start T.V. or whatever, do those things you need to do. Then go watch T.V.

When you are in the middle of something and want to goof off, just think, “when I get finished i can go eat, or watch T.V., or go hang out with friends.”

try motivating yourself with things you want to do afterwards.

Set a schedule of when you want things done, and always have a clock nearby. Maybe you should set time limits on things such as TV and computer, and once you get to work, set goals for yourself. Work for an hour, then break for 10 minutes.
