Improving writing and vocab

Hi everybody
I would like to talk about a way that you can improve your writing and vocab knowledge.
Try to write what passage you read. It is better to write word by word and keep it in your mind what u read, in this way you can actually improve your writing and your vocab knowledge a lot.
In beggining it may sound hard and boring but at first it is better to choose short passages but a complete passage that you can understand the mean of that.
Thank and best regards
