This is a valid criticism (sorry Elon Musk)... By helping the other individual you in the end help society and therefore yourself.

We should be focusing on present problems that are closer to us before moving on to more abstract problems that have less value at present.

The same goes for ourselves. Try not to fix your family or neighborhood before you have fixed yourself (keep in mind diminishing returns). As Dan Koe said: "Your purpose is solving the most pressing problem you have right now." (not verbatim).

Try not to learn how to learn before your sleep schedule is excellent, before you know how to be productive and have habits.

Learning enablers first, THEN learning.

Fix first yourself, then your household, then the city, then the country, then the continent, etc. This does not have to be taken literally, but use it as a wise guidance. It's a principle rather than a law.

What is done right before and right after sleep sets the stage for literally everything.

How you do anything is how you do everything.

Ideally in the evening, before sleep, do some activity or activities that turn off the mind. You want to relax and stop thinking so much.

Interestingly enough, forgiveness, or the act of forgiving makes relaxing easy. So, if you have someone, or even yourself, to forgive... Do this right before going to sleep :)

Apparently, cold shower for roughly 3-4 minutes (rather than a hot shower) before sleep are helpful for sleep, as it decreases the core body temperature.

When you wake up, get sunlight in. Andrew Huberman also advocates for that. It tells the brain and body to wake up. It creates cortisol.

Can be combined with movement/exercise as well which also increases sleep quality. (Movement should not to be too late, however.)

Consistency is key when it comes to sleep.

Always go to bed at the same time and wake up at the same time.

Apparently, some Magnesiums can help with deep sleep.

Author takes 400mg.

It is important to block blue light in the evening. Blue light sends signals to your body to be awake.

One of the things to optimize sleep is to take care of meal timing. Author eats: - Breakfast at 8 - Lunch at noon (12) - Dinner between 5 and 6.30

Discipline and consistency is important here.

Essential is to eat dinner 3+ hours before you go to sleep.

Food increases core body temperature which negatively impacts sleep.

Sleep is the absolute foundation for top-performance.

Measure it. Track it. Optimize it.

After that, results WILL go into the sky.

Huberman states that doing these 4 things consistently and regularly, as a habit, might seem to take time, therefore decreasing performance. BUT, in reality they increase performance, as these things improve your health, focus, and awareness significantly.

Therefore they are so-called Performance Enablers

The 4 (behavioral) keypoints for great physical and mental as well as cognitive health:

One) (2:00-4:05) View sunlight early in the day. The light needs to reach the eyes--increasing alertness, mood, and focus, through certain receptors. Also increases sleep quality at night, according to Huberman. Ideally five to ten minutes on a clear day, and ten to twenty minutes on an overcast day. No sunglasses, and certainly not through windows and windshields. If no sun is out yet, use artificial bright light. Do this daily.

Two) (4:05-6:10) Do physical exercise each and every day. Doesn't have to be super intense. Huberman recommends zone two cardiovascular exercise. Walking very fast, running, cycling, rowing, swimming are examples. He says to get at least between 150 and 200 minutes of this exercise per week. Some resistance training as well for longevity and wellbeing, increases metabolism as well. Do this at least every other day, according to Huberman. Huberman alternates each day between cardiovascular exercise and resistance training.

Three) (6:20-9:10) People should have access to a rapid de-stress protocol or tools. This should be able to do quickly and instantly, without friction. You can just do one breath for destress. ( Deep long breath through nose, one quick breath in nose to completely fill the longs, and then breathe out through mouth long.)

Four) (9:12-14:00) To have a deliberate rewiring nervous system protocol to use. A thing that can be done is NSDR (Non-Sleep Deep Rest protocol), this is specifically to increase energy.

Ideally the NSDR should be done after each learning session as well to imitate deep sleep (REM) and therefore accelerate neuroplasticity and thus rewire the nervous system; increasing the strength of connections between neurons and therefore increase retention significantly.

NSDR is also a process of autonomity and control, it allows one to find that they are in control of their body and brain. It makes one realize that external factors don't necessarily have influence. According to Huberman, NSDR even replenishes dopamine when it is depleted, making it also suitable for increasing motivation.
