What is your mantra or system to achieve that?
I have a regular sleep and wake time that remains roughly the same daily, and I practice good sleep hygiene. I cannot stress enough how good it is for your brain once you get it into a solid healthy sleep routine.
I also have a lot of long-term goals that revolve around achieving long-term happiness (which, as someone with ADHD, has been hard to achieve this kind of mindset because I generally crave excitement and fun today at the expense of anything to do with the future - I've had to mentally train myself to ask myself in any given moment "how will I feel about this decision in 48 hours?"). I also wrote my goals onto paper and put them in a place I see them every day to remind myself because otherwise, I generally only think about the present moment, so having long-term goals and reminding myself of them regularly serves as motivation to get things done and reduces my tendency to procrastinate.
I also embrace the third space theory, irrespective of whether there is evidence for or against it. I like to operate my life in silos. I keep my work, family, and social life separate from each other, which I find incredibly liberating.
Finally, I no longer use mainstream social media for anything, and I generally prefer to acquire knowledge about how the world works through my academic pursuits to think critically about the information-obsessed world we live in.
