Try a different method. It does not mean you are stupid. It just means you were trying the wrong methods. :)

It's possible.

每个人不一样吧，别勉强自己。如果你让我读汉字的话，我也需要花很长时间读的。漫漫来。我们俩加油！ :)

You are not stupid. You try to do your work with quality mark you are realy a hardworker. But I think your work needs some kind of inspiration. You must tune for creation just connect to your mind, think wider then your colleagues and you will do any task better and more quickly.

The slow need to start early., believe in yourself, you are great.
