Outdoor distractions can waste a lot of time if you let them go. An outdoor detour is an unplanned activity that interrupts the task you are working on. For example, if you are engaged in a report in the morning and a colleague asks you to call a customer to solve an immediate technical problem, this is a distraction from the outside.
The key is to block side distractions as much as possible by closing the door, keeping your desk away from bystanders, responding to your voice mail, seeing a “No Distrub” sign and working from your home part of the day. or ask people to shut up. Your mind may be able to rule out a lot of signals if you say so.
If interruptions are a real problem, try to reserve an hour each day to meet people and answer calls. The rest of the time is a “private time” where you can work without interruption. Most people say they do more if they work continuously as long as they want.
The main idea is to do things on your calendar, not those of others. It is not always possible. But the more you control your time, the more you control your life.
