Manage your time. Write the bureaucratic chores you hate on a list and do one the first thing every morning. Check it off and reward yourself by doing Extension work the rest of the day. Get control of you time and your professional life. Manage the boss.
Motivation is a two-way street.
The more you express appreciation for and reinforce supportive administrative behavior, the more you're going to get. Criticizing the boss usually brings on a defensive reaction and changes nothing. Go along and get along. Most Extension administrators were once pretty good agents or specialists. If occasionally one of them has an idea that still works, give it a shot.
