There are endless systems, tools, and strategies.

Carefully consider your environment. I perform best with very little going on around me. In my physical environment and on my PC. Austere. Minimize things that catch your brain and eye. One or two apps at a time, close everything else. Pick your one more important thing every day and work on that. It needs to be a contract. Usually you have one or two important things to be doing and you can ignore everything else without too much consequence.

To remember things you need an ironclad todo system that lets you very quickly capture anything you need to remember. You need to be able to record, triage, filter, prioritize, and execute on anything you need to remember. If any one of those stages is leaky you won't trust it and it won't last. My entire life is structured around managing it. I have to have very strong discipline. House must be spotless. Desk must be spotless. Try to work in the same place at the same time every day. Environmental and contextual stability is huge. Your brain must associate a particular desk, chair, place with doing the most important things. If you allow yourself to goof off or do other things in that place you are losing the fight.

Working out fixes a lot for me too. I workout or my mood and motivation falls apart. Move or die. Again, consistency is key. Everything I do around environment is to reduce the need to use executive function. It is finite and fickle for people with ADHD. The more you have to think and convince yourself to do things the less likely you are to do them. You need consistent cues. "Sit down here, start timer, means work on main thing and nothing else." If you can have discipline at all of these external things, the work can just happen and there is a kind of freedom in that.

Program outlets. Give yourself set, specific time to explore the sidetracking. Don't tell your brain no. Tell it "later". It helps if you know there is time for the extra thoughts. That there is a relief valve.

Also, drugs. I use prescribed stimulants. There are some unpleasant negative things, but I can function with them and life is better with them. But it isn't some magical cure. You still have to be organized and willing to work on your tasks or you will just be really focused on things you don't really need to be doing.

I could write so much more, but that is some top of mind stuff that I think sits at the top of my hierarchy of being productive. Oh and you may need to have some conversations with future you. How is future you, a week, month, year from now going to feel if you burned a lot of time on side quests?
