When you're in doubt, zoom out
They always say:
When you're in doubt, zoom out.
For example: You might not be productive this week, you had many interruptions you didn't achieve much, so that turns into you believing you're unproductive in general.
But, when you zoom out to take a look at the overall progress and performance, you might find that during this month you've achieved and progressed much.
So, never forget the rule; "When you're in doubt, zoom out"
