Very Early in my career by bosses job was 90% running reports for others. A solid 7 hours of work each day. She spent 2 weeks teaching me how to build the reports then went on vacation. When she got back the reports were a 5 minute job. She proceed to use her now mostly empty day to have teach her to program. Then started taking on more responsibility in the company. I got a 25% raise.
