This might be a bit off topic, but might help somehow... Something that has striked me during the last weeks --since I got my WHOOP-- is the correlation between HRV and self-control (aka. will). I've monitored how productive and focused I am and my top days all have in common this: -- didn't drink alcohol at least 3 days before (I'm now avoiding it as much as possible) -- got at least 3.5 hours of REM and deep sleep -- breath exercises at least 3 time a day Conclusion... monitor your HRV and you might be able to focus better
