Need basic tools and ways to practice and polish my writing skills
What are the ways to practice and improve basic writing, like content and creative writing? I am not planning to write or learn to write fictional stories. By creative writing, I mean the essentials of writing anything is to first be creative. Any good writer is witty, eloquent and creative. Though my Grammar is excellent technically, I can write on the topics of my interest. But I lack the key writing skills. I need to learn and practice my creative writing skills, which I think is the key to writing well. I want to be able to write a blog where I can write on anything without having to spend time over it.
Furthermore, I am reading "The Elements of Style" by Strunk, Perfect English Grammar The Indispensable Guide to Excellent Writing and Speaking, and another book on Grammar. I am using the Language tool extension, for basic correction. Can you please give me some basic sources to practice my writing skills? Such as some great YouTube channel, or a website which gives exercises or provide something to learn by copying. I hope this Question is specific enough for the rules, and it will be beneficial for many readers as well who are just beginning their literary journey.
