You need to figure out what to ignore and what to pay attention to.
But which is which?
It’s best to ignore things that are outside our circle of influence.
Some examples for sales people to ignore:
Your company’s past performance: ignore the past. Only focus on the future.
Politics at work: keep away from office politics.
Products you cannot sell: don’t waste time on products that are not ready for market. The successful ones will help you reach your target.
