I am a working professional and English is my second language. I realised that my vocabulary is very weak so I started reading. I don't have enough patience to complete a novel so I started reading Quora answers and magazines like Forbes, Reader's Digest.
It's evident that my vocabulary is improving as I am maintaining a diary and write every new word/phrase that I come across. But what about my writing skills? It will take me an hour to write a decent review of a movie I recently watched. I am not able to use good words which I already know and my thought to sentence conversion is also poor. Could you please suggest me some exercises/methods to improve my writing skills?
