I play a long-hour drilling sound and I don't turn it off until I'm done
Open YT, search for a ten-hour loop of concrete wall drilling. Lol I swear one particular video will appear. Set the volume to a level that vibrates right through your earcups and THE TAB STAYS PLAYING UNTIL THE WORK IS DONE. Clear?
Embrace the relentless screech of a heavy drill grinding directly onto your skull. (Think of a virtual lobotomy.) The bzz/whirr sound will make your skin crawl for shre, but realistically a person can resist. It did happen for me.
That brief sensory torture (unless you took the ten-hour study sesh seriously ..) will be worth it. Trust the deed!
