A productive day is what you make it.
If you sit around all day watching YouTube, and that’s what you set out to do, then you’ve had a productive day.
If you go out for lunch, and that’s what you set out to do, then you’ve had a productive day.
If you choose to focus on one particular task and nothing else for the entire day, and that’s what you set out to do, then you’ve had a productive day.
What defines a productive day for you is always going to be changing. Every day it will be different.
The key is to know at the start of your day, what will define a productive day by the end of it.
Know that and you can then do whatever you want to do without feeling guilty or anxious about what you are doing or where your time is going.
