Why can't I focus — even on things I want to do?

It's not that you're lazy. Focus is a physiological state, and yours might be blocked by things that have nothing to do with willpower.

Why it happens

Dopamine deficit — the reward chemistry that makes focus feel possible is low
Overstimulated environment — phones, tabs, background sound compete for the same neural bandwidth
The task is boring — ADHD brains struggle far more with 'important but dull' than 'interesting'
You're under-slept or under-fed — the brain literally can't sustain attention
Overwhelm shutdown — too many open loops causes the system to freeze

1
Body first, then brain
Water, food, one lap around the room. 5 minutes of body reset beats 30 of forcing.
2
One tab, one task
Close everything else. Overwhelm is the enemy of focus.
3
Body-double or timer
External accountability tricks the brain into 'go' mode.
4
Start with 2 minutes
Focus is easier once you're moving. Motion first, focus follows.

Is my focus getting worse?+

Attention capacity varies with sleep, stress and hormones — a bad week doesn't mean decline.

Do focus supplements help?+

Some (omega-3, caffeine) have modest evidence. None replace sleep, movement and reduced stimulation.

Should I get tested for ADHD?+

If focus problems have been lifelong and affect multiple areas, it's worth exploring with a clinician.
