改善方法!!help me please!

我都有呢個問題。

我會一清早將每日要做的事列出來，將重要的要先編排好，如此類推。

粗心大意跟經驗有關，唯有提醒自己，不要太快做決定，粗心大意的人最好的訓練方法就是少發言，少發表意見，多觀察。總之，以靜制動，少成為群眾焦點，就會保護自己了。

I got a solution for your third problem.
For instance, when you are doing a test, you can read the questions line by line by using a ruler to underline the line you are reading, or simply mouth the words without making any noise.
When you often forget to take things to school/ do your homework, write all the things you need to bring to school tomorrow/the homework you need to do in your handbook, and put a branket next to all. When you finish doing something, you put a tick in the blanket.
That is what I did.
Yet for the first and second problem it will be up to you. It all depends on whether you really want to change yourself, learn to hold your impatience and distraction. You have to learn to take control over yourself, remind yourself for always that you need to concentrate and be patient---this is the only solution. Take patience in every proccess you make, and every goal is possible to aim.
