1 (just the one) Tip for Getting Better at Writing

You don’t start out writing good stuff. You start out writing crap and thinking it’s good stuff, and then gradually you get better at it. That’s why I say one of the most valuable traits is persistence.
— Octavia Butler

Ain't writing cool? It can change the world with no bigger investment than a few minutes a day at a keyboard. It's a simple as typing "lol" in to a text message, and as complicated as writing a moving speech about cooperative business in Africa. You can tell a story about elves and trolls, or tell one about tech industry entrepreneurs and tycoons, and both stories can change the world. 

Want to get better at writing? Do more writing. Every day, no excuses, no delays. Sit with your thoughts, and put them on the page. Forget the trappings of how you write—don't worry about whether you should write on a computer or on a notepad. Don't worry whether you should be funny or serious. Don't fret over spelling or grammar either. That stuff comes after writing, not during. You fix mistakes when you edit, not when you write.

Writing is something else. It's immediate expression, without a filter. And you have to do it again and again, and make mistake after mistake, before you really, finally, honestly get good at it.
