Also ADHD here, I have the same problem.

The only way I can get anything meaningful done outside of work is to do it before work.

Those first few hours of the day are precious, as far as energy goes. Or attention, or will.

On a related note, I put Q2 of Eisenhower Matrix (important but not urgent, i.e. the stuff you want to get done "someday" but keep putting off indefinitely... i.e. your hopes and dreams) at the front of the day, because Q1 (urgent and important) basically forces you to do it and requires no special attention.

To put it bluntly, the long term stuff needs to be scheduled and consistently acted upon, or the default outcome will be very depressing.

I schedule it first thing, every morning.

never heard of the eisenhower matrix but my time management resonates with what you wrote. ill try forcing q2 stuff earlier as well as ive noticed it never gets done! yes, the default outcome is depressing.
