帮我看看这篇英文有没有什么语法错误

我给你修改如下：
Time flies without pause.You may have many dreams.we live for dreams.Now that,the past has gone,no need to remember it.the future has not come yet,no need to worry it.living at present,try to make your everyday beautiful.Time flies,we should seize it.The key is :you should have an open mind ,free attitude ,free action,free love and free dream.Freedom is so important ,not only for your body but your mind as well.Seize the time,seize the chance,save your life and make your everyday colourful!
