Yes, I relate! I know everything but can't apply it.
I also have ADHD. There are plenty of threads all over MN at the moment about how "everyone can't have ADHD!!" and bemoaning people sharing their experience but I will share anyway, in case it helps you.
There is procrastination, that is normal, everyone does it, usually these common techniques will help to some extent. If you find that ALL techniques fail, or feel that procrastination is controlling YOU rather than you being in control or it's actively creating negative situations/consequences in your life, then it might be worth looking at underlying causes (which could be depression etc not just ADHD).
For me, the solutions that work are often counter-intuitive or opposite to what most people find helpful.
For example:
Break tasks down into smaller sub-tasks. No, even smaller than that. This approach makes most people feel overwhelmed because suddenly their to-do list is ten times longer. For me, it makes each step much more manageable. However, the process of breaking the task down also uses up a huge amount of processing ability, so it's most helpful to do it for recurring tasks (e.g. cleaning the kitchen, making a phone call) and SAVE THE LIST somewhere to use next time you need it.
Also, giving myself permission to just do as many steps as I can manage, then stop. For example the steps for making a phone call are:
- Find the correct phone number(s)
- Plan out what I will say; write notes
- Make the phone call
- Write down the information or follow up task
The steps for posting a parcel are:
- Locate the items to go in the parcel
- Locate correct sized envelope or box
- Weigh or measure parcel to find out postage
- (If necessary, communicate postage costs to buyer/confirm)
- Pack the parcel
- Find the correct address
- Address the parcel
- Buy the postage
- Stick the postage on
- Place the parcel near the front door/on the buggy
- Take the parcel outside
- Place it in post box
I might do all of those things in one day. Or it might take me several days to complete all of these steps. However, if I am constantly thinking I can't half do a task, if I pack the parcel now then I have to take it to the post box now, that ca noverwhelm me to the point I freeze and don't start. Equally, if I need to go near the postbox I can become consumed with guilt about this parcel and not be able to get myself to put it together, that will also add stress to my leaving routine in general and contribute to the likelihood of me forgetting something (sometimes the parcel that I have panic got ready at the last minute!) or getting impatient with DC or leaving late or forgetting to do something important last-minute such as change DC's nappy or brush my hair or take the key out of the door.
Although it's not ideal when it takes me up to 11 days to post a parcel, that is still better than it getting forgotten for weeks and weeks or stressing me out consistently.
I can't use pomodoro timers. The idea of interrupting myself after 25 minutes is great but I can never stick to the 5 minute break - I will simply never return to the original task. Sometimes I can do reverse pomodoro, that is doing a short amount of work with a long break interspersed all day, but standard ones don't work for me personally (they do work for some people with ADHD, this seems to vary)
When decluttering/tidying, take it there right now - I used to try to organise by getting everything out and trying to sort it into piles. I think I'm being efficient in doing this because at the end of the organising session, I can just take one trip to the place where that pile lives, right? In reality, I rarely ever complete a whole task and when I do complete a task, the thought of doing that one last step (put the hoover away, take the pile to the correct room) is like climbing a giant wall, so often I think "I'll do it later" and then trip over it for days until it slowly disintegrates into a general mess again. Now when I am tidying/organising, I take whatever I have found in the wrong place to the right place immediately. It means that I probably take fewer things out of the place I'm trying to tidy/organise than I used to with my pile method, but I always finish putting away that one thing. If I remove 10 items and put them in their proper homes, that's better than if I remove 30 items and place them in piles on the floor where they continue to exist as more mess.
Start with the easiest task - the common advice is to "eat the frog first" - ie start with the hardest, gnarliest task that is bothering you the most. The idea is that everything after that will seem easy and you'll save stress. For me the opposite is generally true. If I try to start with the hard task I will ruminate and freeze and be unable to start. Start with the easy tasks and working my way up to the scary/gnarly one works much better.
Remove/add barriers in order to change motivation - I'm highly susceptible to the power of suggestion and easily distracted. I put stuff that I need to remember where I will see it - keys ALWAYS and ONLY go on a hook by the door, it's the first thing I install in a new house, and make distracting stuff harder to access - I turned all notifcations for social media off on my phone, removed all shortcuts on the main screen, added widgets for productive things instead and keep changing the way it sorts apps on the app screen so I can't use muscle memory to automatically open Facebook 100000000 times a day. I put my guitar next to my computer and added songs that I want to learn to play to my main playlist and that works well at getting me to play! I have a vacuum cleaner that I can easily grab in and out of a cupboard because getting out a large one that involves moving furniture = will only do it when I REALLY REALLY have to.
Magnify long term goals, gamify short term ones It's normal for everybody to find that short-term rewards (eat a cake now) more enticing than long-term goals (stick to diet plan, lose weight) but this is exacerbated in ADHD and anything long-term seems to be so far in the distance it is a tiny speck on the horizon, whereas "right now" seems to blink in our face like a lighted up neon sign. If you struggle with this you can help by creating some kind of visible, tangible, very real feeling mood board or other anchor for your long term goal, and then breaking down small pieces of progress towards it and looking at ways to incentivise yourself to complete those. I don't seem to be able to self-reward in terms of e.g. "If I write 100 words, I can have a cookie!" which brings me to the next tip:
Rely on external cues and rewards I managed to get to school on time during secondary school by being a slave to the TV schedule. If I got downstairs in time for Friends, I could get dressed in front of it and leave when it finished. If I was slower/later then I would miss the programme. Inviting people over so that you have to clean is a valid motivation.
Here are some more examples of things that would help most people, but do the opposite of help with ADHD:
