When you run a business, your job is not to micromanage or do everything on your own. At the beginning, yes you are the one who finances the company, creates the products and sells them. But as you grow you should delegate these tasks to others, whether it be through employees or through outsourcing.
The important thing to keep in mind when doing this is to provide proper training to employees. If you want something done right they say that you should do it yourself. However if the only tasks your employees do are menial, repetitive, non creative tasks then there is less they can do wrong.
Remember that as a business owner your job is to assure the continued strength of the company. It is to create new products and be the creative leader. It is to provide a vision. So the next time you’re slaving away doing a repetitive task, consider outsourcing it so you can concentrate on more important things.
