It’s my great honor to have the opportunity to share with you my opinion on time management. None of you can deny the fact that managing your time effectively is of critical significance, which can minimize your stress, boost your performance and promote your self-confidence. Such being the case, how can you achieve this goal? Firstly, what you need to do is to plan ahead, thinking about upcoming events and making a to-do list. Additionally, getting well organized is a must. Most importantly, you must learn to prioritize all your tasks, focus on the goals and stick to them. To bring my presentation to a conclusion, let me quote what Lu Xun said, “Time is like the water in a sponge. If you are willing to squeeze, you will always get some.” Thank you! 总结 测评 Thank You 07 Unit 2-1 FLTRP 英语选择性必修第二册 2020 other 293428.16 $
