Is it OK to say "you should try to get a good night’s sleep however much work you have to do"? "You should try to get a good night’s sleep however much work you have to do." This sentence sounds weird, doesn't it? Could anyone help me revise it? Thank you!

Tim Duncan Retired Days ago, Tim Duncan announced his retirement. That means he will not play in NBA next season and forever. I'll miss him a lot. He was a great basketball player, who played for nineteen seasons for San Antonio Spurs, won five NBA Championships, and got three FMVP titles and two MVP titles. He has been in All-Star fifteen times. He was absolutely successful. What mostly astonished me is, he acted like he had almost the same ability through his whole career, which only a few people have done. In 2014, the year Spurs won the champions, 38-year-old Tim Duncan played as active as he did when he was younger. However, this season Tim Duncan showed the affects of aging, which is the most important factor that motivates his decision of retirement. I am very grateful to watch all your games, and I want to show my most sincere respect to you. The hero of Spurs is gone, but I wish Spurs will perform well next season.

How to learn English? Now I am studying in an international school in China. Hopefully, I will go to a university in the US in two years. I will take TOEFL next week. It will be the first time for me to take this test. I am kind of nervous. I am not sure whether I can do well. I really need to improve my English language proficiency. My speaking is not very good. Could anyone give me some suggestion on how to improve my English? If you are not a native English Speaker who can speak English very well, please tell me how you learned English. Thank you for your helps!
