||Get plenty of rest. A good night's sleep will not only ward off illnesses, but will also make sure that your mind is crisp and ready for the daily tasks that lay ahead of you. Not getting enough sleep can make you irritable and cranky, and it can literally hinder everything that you do. Don't skimp on the beauty sleep.
One of the best ways to succeed at making big changes is to break it down into smaller and more manageable components. Don't set out to run a marathon! Start out with running a mile, or a 5k. If you don't set goals that are within easy reach, you're bound to get frustrated by the lack of progress.
If things are not working out the way that you were hoping that they would, stop and rethink your approach. If you have set a plan that is not succeeding, rewrite that plan and make the necessary changes that will help change the outcome. It may take more time, but it will be worth it.
