[Method] you don't need mindfulness you need this.

Look it's great in theory to use what fading wilpower you have and just drive through discipline but reality is wilpower gets fatigued through out the day, discipline is a muscle and let's face it we aren't david goggins here so how about using something that will actually work.

You need blockers, Timers and a schedule that can actually block out the distractions not some passing inspiration on a platform who is literally paid to try and make it as distracting and addictive as possible because that's how they get paid.

I'm not affiliated with any of the recommended apps but I highly suggest them or at least something like them.

Getcoldturkey.com - website blocker for desktop

Freedom app - blocker for phone

Liferpg, habit hunter, do it now rpg to do list, task game, etc. - some type of Gamified to do list

Finally you don't have to treat yourself like a prisoner, pomodoro technique can be good and so can rewards. The trick is too just find a balance.

I'll leave off on this: a little each day quickly adds up

30 mins per day = 15 hours after a month of consistent work

1 hour per day = 30 hours per month (damn near an actual work week)

Hell even 5 mins per day can add up to a tremendous feat given enough time and it's a hell of a lot more than doing nothing and pushing it off for another day.
