bad time management

well, the title says it all.

i've had pretty bad time management skills since primary, i just can never seem to get any work done properly, though my brother just says im lazy asf lol (which i agree on) anyway, im in the middle of GCSE's and hopefully will be starting my A Levels and with the mindset of 'ah i'll do it later' i'll end up with C's and D's throughout.

i really need good tips on how to manage my time properly and how to stop procrastinating..

thanks a bunch

1) Identify
Remind yourself that there’s always more to be done than can be done. Then ask yourself if you’re getting the right things done.

2)Plan
Make a smart to-do list by including only the items that you’re avoiding, not the ones you know you’ll do anyway. Then set deadlines.

3) Break it down
Break the task down to lessen the sense of being overwhelmed. Once you start to enjoy a small accomplishment or two, you’re more likely to finish.

4) No distractions
Eliminate temptation to do something else, turn off computers/phones or put them in a different room AND LOG OFF TSR!!
