Time is the one true currency why do you want to waste it? Learn to program or run linux but donr have the goal of i gotta learn this have the goal of i wanna learn this so so i do xyz fun thing with it. I mean u could always get a mindless job and u would be earning money that why ur productively wasting time. Learn to cook good food. Go touch grass and walk hell just go have a shower and go stand in the sun. Work out doesnt need to be much. Let yourself get bored let yourself reflect and think escapism leads to hate leads to suffering leads to alcoholism leads to the dark side.
Make urself a checklist of thing to do every day. Not goals to achieve but things to do that will slowly work u towards those goals. Then aim to do more than yesterday dont stress it if u fail as long as u did soenthing.
As Jordan Peterson would say go clean up ur room and make your bed.
Weed also works extremely efficiently at making doing nothing enjoyable. I heard opioids also make doing jack shit easy.
I dont recommend any of these as a solution see my above comment but this will work if ur ready to commit yourself to a homless miserable life offering blowies for $5 and a pack of smokes.
Then again worse case scenario killing oneself is always an option, ita not a good one i ask you please dont under any circumstances do so. But it would make time pass exceedingly quickly (well depending on ur religion or if u have one etc)
