How Can I Get Better at Writing?

Andi says writing is the same as listening and reading everything else. If you don't write, you're not going to get better at writing. Don't write the first thing that comes into your head - think about it in real life. Think of who am i writing for? Why am i writing? What's the purpose? Who am i interacting with? And that will determine the style, or the register, how formal or informal your writing should be.
