how to get good mark in sports.
in recent years many people try to do muany sports because it's good for your health and also can keep your weight.
but some people regard sprots as a competition not like a entertainment.
They hope to have a better mark and good record. i think if when you have a competition ,the first thing to do is keep relax do not feel so nervous and you must believe yourself have confident. so that you can obsolutely get a good record and mark.
otherwise, you will feel upset and nervous i positioning believe you will not get any good mark.
anyway i positioning believe that believe yourself is the most important reason to get a good mark!
