If you’re out in the desert with a .22LR rifle and 1,000 rounds of ammo, you have a choice. You can start blazing away at every random rock you see, or you can set up targets and start aiming.
Blazing away just makes noise. If you like loud bangs and you think noise means progress, good for you. Not me. it’s a waste of time and ammunition.
Set the target. Then pull the trigger.
This has application in my daily life. My calendar shows blocks of time, what I’m going to work on, and what I intend to achieve in those blocks of time.
I might miss my target. But I have a target. I won’t waste that two hour block of time. I will get something accomplished. And it won’t be by luck.
