Remember that owning your own business is not the same as being employed in a job. Some people go to work and coast along, playing games or enjoying online social networking (Facebook and the like), some socialise over the kettle or printer, and others, most often those who are paid in a commission or tip environment, go to work to work to make money.
When you work for yourself, what you make in terms of income is directly proportional to your productivity. Therefore, wouldn’t it make sense to stay focused on getting as much done in as short of a period as possible? Go to work to work and to make money. Leave socialising for when your workday has ended.
