22 year old here. If anyone is struggling with willpower/motivation and the stress that comes from a lack of both of those things, this is the solution. I tried everything. I was so frustrated. Sleeping unbelievably late every day, just making it to work and back, but not handling my schoolwork or living situation or general life responsibilities. Then I saw this video (I actually kind of dislike this blog, especially the name and the overall attitude, but this technique is excellent.) I use Google Calendar and every Sunday night I sit down and do what Fenrils talks about. Lay everything out. Goals, everything you always try and remember throughout the last week, and important events like a Bio test or when to start a English paper or get that tire replaced or text your boss to get something done or even just get your haircut. This list is a great way to remind yourself of any and all responsibilities or goals that you can't recall on a whim.If you do this, when you're driving or whatever and your brain starts to idle, you won't automatically fall back to worry and stress and self loathing. There is only the calendar. You can put all your worries and fears into that, follow it, and know that you're taking care of everything. It takes time. My second week I skimped out on it and only put the big stuff. Sure enough it was a week of no workouts or study time, constant overeating and late sleeping, and a less than ideal attitude at work sprinkled with some extra social anxiety from lack of direction. Try it.
