Strong Writer, 19 Years Experience with Formal and Other Styles
The best advice I can give is what not to do. When I was learning how to write, how to really write, our teacher gave us a list of words we absolutely could not use in formal writing, along with other practices that were off-limits. Giving yourself a limitation to start, and forcing yourself to practice writing formally with these bounds may open you up to many other forms of writing in the future.
Some of the words you absolutely should not use in formal writing are: any form of get (got/gotten/getting/gets), world, worldly, thing or things, someone, anyone, no one, somebody, anybody, nobody, anything, something, nothing. There are a few more.
Some practices you could also implement are:
- Eliminate sentences that start with 'This...' Such as 'This shows that the dog, indeed, had rabies.'
- Eliminate any 'be' verbs, but use only two or three per essay if you must; so words like "is, are, am, being, been" etc. need to be removed.
- This may seem crazy, but eliminate the word 'and' as much as possible. Might be the most challenging item on this list, but it can be done.
- Don't go too overboard with commas. If you have any doubts a comma should be there, take it out.
- I can't help but point out that formal writing loves present progressive verbs. So, rewriting the sentence 'I assisted my mother with her chores and then the doorbell rang' to something like 'Assisting my mother with her chores, the doorbell rang' will help your writing become tighter, more meaningful, and focused.
Also remember, if you cannot read your own writing without your mind drifting, your writing is not engaging enough. I can't recall how many books I've read where this happened to me; only about 10% actually captured my attention for the story's duration (mostly Stephen King and Douglas Adams). I implement this 'mind wander-proof' practice with film theory and criticism too, along with content creation and video editing.
