1. You are not writing a movie (ignore this if you are). The reader doesn't need to know every word the characters say for the duration of the story. Less is more.
2. Dialogue can happen within the prose. "And they awkwardky discussed the weather for five minutes" is way better than actually writing five pages of dialogue about the weather.
3. Balance your dialogues. Surprise yourself with a monosyllabic answe to a dialogue that's ten sentences long. Don't be afraid of letting your character use half a page for a reply or nothing at all!
4. Don't write accents phonetically, use slang and colloquialisms if needed.
5. Comma before "said" and no caps after "!?" unless it's an action tag. Study dialogue punctuation.
6. Learn the difference between action tags and dialogue tags. Then, use them interchangeably (or none at all).
7. Don't be afraid to use said. Use said if characters are just saying things, use another word if not. Simple. There's no need to use fancy synonyms unless absolutely necessary.
8. Not everyone talks the same way so it makes sense for your characters to use certain words more often than others. Think of someone who says "like" to start every sentence or someone who talks really slow. Be creative.
9. Use prose to slow down the pace during a conversation.
10. Skip prose to speed up the pace during a conversation.

I just want to add a quick disclaimer that I have not been diagnosed with ADHD myself, but I have worked with several clients who struggled with this, and done some research online to compile a few tips you might be able to implement in your writing! (I will also link to some articles I read at the end of this post).

1. Turn off the internet This popped up as one of the most common pieces of advice for ADHD writers. Eliminating distractions can be hard, but turning off your wifi altogether might help with at least a few of them. Train yourself to disconnect when it’s writing time, and see whether this affects your productivity positively!
2. Delay the research This can be really difficult if you’re writing historical fiction, or anything set in an area that requires some level of prior knowledge to write about. But, wherever possible, if you can save yourself pausing to research whether a certain item or word is plausible for you to use in that specific moment, then you should. Leave it, make a quick note that that’s something to research later, and keep going.
3. Test out radical changes Something that came up as a common downfall was losing interest halfway through the project, or dropping it after the first chapter. If you find yourself losing interest in the project, maybe try out making a radical change to a part of your plot, one that might inspire you for the story once again. Of course, make sure that this change fits in with the rest of your story as you begin to implement it.
4. Succinct & clear goals This is something I recommend to any writer or artist of any kind! Keep your goals as clear and small as possible. The more specific you are with a goal, the less overwhelming it will feel. Think of breaking down a big goal of “I’ll finish my book this year” into “I’ll finish 5 chapters this month” or even “1 chapter this week.” Go as small as is comfortable for you!
5. A fine line between plotting & exploring This is an issue that comes up very often for writers who have a tendency to get bored with their projects if they don’t keep some element of surprise to it. I’d recommend finding a good balance between how much you plot out, and how much you allow yourself to discover along the way. Find your most important plot points, and let your creativity fill in the gaps!

• Mob: mostly simple attacks, not very showy, just waves his hand and uses telekinesis/exorcizes something, doesn’t move around much. As ???%, much more destructive, psychic force seems to just emanate off of him and destroy everything
• Teru: VERY mobile, throws himself around with telekinesis, puts his whole body into the attacks and tends to use moves from normal fights (punches, slaps, kicks, etc). Utilizes a variety of psychic techniques with flexibility, very creative. Piss stance, necktie sword. Much more flashy than Mob
• Ritsu: uses powers to throw people/things around. While Mob and Teru attack with just psychic blasts, Ritsu tends to use his powers to grab other things as an attack (grabbing the delinquents and throwing them against each other, throwing the Claw guards against the wall, picking up cars to sandwich Shimazaki between them). Uses his environment creatively (fire extinguisher smoke screen against Shimazaki). More flashy than Mob, but not as mobile as Teru. Hand gestures for Drama
• Shou: sneaky + speed + bomb!! Tries to be as evasive as possible using invisibility/speed (probably telekinetically enhanced?) to hit from behind, using either telekinetic force (his stomp in his introduction, the shockwave hit on ???%) or his charge bomb attack. Potentially uses speed/evasive moves as defense instead of the barriers we see most everyone else use
• Serizawa: likes to channel his powers into an object (umbrella, business cards). Uses that object as a shield, sword, or something to blast psychic powers out of. Not very mobile in season two, moves around much more in the yokai fight. Not particularly flashy, but looks cool regardless
• Reigen: deception/surprise!!! Either tricks people into thinking he’s going to do something else and then attacking, or just outright taking them by surprise and attacking before they know what’s going on. Usually doesn’t have a follow-up move, just does the one attack and hopes for the best. Prefers to bluff his way through a situation
