Proper time management is a great way to get rid of stress. One of the best ways to manage your time is to get a head start. The earlier you start working on your task the earlier you'll complete it and with that you'll be able to go through it thoroughly to ensure it is error-free. It also reduces your stress because you won't be trying to meet deadlines.
The other thing to keep in mind is to know how to prioritise your work. To-do lists are great as they give you a clear view on everything you have to complete and how urgently it needs to be completed. It helps keep you focused on what is important and doesn't make you feel bogged down with too much to do.
Focus on one thing at a time. Don't try and do two or more pieces of work at the same time. It can be overwhelming and hinders productivity, causing you to slack off instead of getting more done. Giving your undivided attention to a particular task not only gets the job done but at a better quality.
Breaks are essential when you're feeling stressed. It helps you clear your mind and freshen up. A short 10 to 15 minute break can help boost your concentration and productivity by miles.
Take it a day at a time. Learning to manage your time will not happen overnight. But with consistent practise you'll be able to master it and greatly reduce your stress.
