@gray-beach-48055 There is no magic bullet to it. You just have to write a lot + get feedback.
Communication is nothing but trying to get ideas inside your head into someone else's head. I am guessing you would mostly communicate via your writing (unless you make videos).
So I would write a lot and seek feedback from my recipients. Whether it is a blog or an email, you can drop in a line to your immediate manager or colleagues and say - Hey folks, I am trying to improve my communication skills. Can you please fill up this form <link to Google form> with some basic questions that you need help with.
You could also enrol in communication classes. Either online or offline. If you stay in a city, these should be easily accessible.
I remember reading "letter writing" books and mock letters when I was in school - which is always a good exercise to see how good authors present their views eloquently.
However, if you want to be a better communicator, communicate more (i.e. write + share + get feedback)
