A few things to consider if that’s the case:
Everyone has 24 hours in a day, even the most successful and productive people, however you measure success and productivity. That includes people who run many businesses.
Certainly some aspects of scheduling are less in your control than others, depending on what’s going on in your life. If you have children, for example, you have inherently agreed to sacrifice at least some of your time for them.
(How you schedule your children’s’ lives is something that should be open to examination, however. But, understood: it’s not easy. I have two myself.)
But that doesn’t account for everything.
There are also rushes that you create for yourself, unecessarily.
Like, the ones that occur when you try to do one or two more things right before you should be leaving, or resting.
Instead, when you’re up against a hard time obligation, such as a meeting or appointment, sometimes doing one less thing is far more productive.
How can that be?
It is so because it makes you choose only the most important thing.
