Focusing and doing some effort to get things done.
You don’t need to work all day.
But you need to do some focused work for at least 2 hours every day.
And I assure you that a lot of people who work 8 hours per day never do 2 hours of really deep work.
If you manage to get 4 hours of those focused and high-value hours,
It’s already more than enough for most goals!
And we don’t even keep our mental performance at its peak after these 4 hours, probably not even after the first 2.
But it needs to be real focus, get rid of all distractions, and get to the main problem, that’s it.
