How do you make time for life?

Okay so I have a bunch of friends who fall into the below 2 buckets:

1. Doesn't have a very demanding job, therefore can take out time for plenty of other things as well (pay isn't the highest and they're ambitious for more too, but right now they are sitting proportionate to their efforts/skillset/experience)
2. Genius, 10x contributor. Gets shit done in 3-4 hours max. Enjoys the rest of their day. (Pay is bonkers of course and naturally such people are rare too)

Now, there's a 3rd bucket that I think I fall into:

3. A very demanding job (~9 to 9) and pay is also proportional to the hours they put in, so it's in between the above 2. These would probably include roles like Product management or any type of people management roles as well where you overlook an above average level of uncertainty. Now, 12 hours of work (with some breaks as well), 7 hours of sleep, 1 hour of commute, 1.5 hours of eating etc, 1 hour of workout (asking for too much here) and that's pretty much the end of the day.

Now, I think the distribution of people in these buckets would be as follows:

1. 70% (basically everyone that is 'starting out')
2. 1% (hence, they are 10x)
3. Remaining?

How do people in bucket 3 take out time from their lives to do basic things like:

1. Being with their family
2. Socializing
3. Rest (how else can I work for 12 hours without giving out garbage output?)
4. Growth? (I have only been in corporate for a short time, but I am crystal clear on the fact that no company cares about your personal growth. They might even push you towards being utterly dysfunctional elsewhere, so that you don't churn, but never the other way round. If you can, as a side product, get personal growth from meeting their goals, you're lucky. Otherwise, always be prepared for the worst)
