If you've ever worked alongside someone whose financial life was imploding, you understand the value of employees who have their shit together.
My bosses have all wanted the same thing.
1. Keep their phone from ringing.
2. Don't be too distracting, but do interact with your coworkers.
3. Have goals.
4. Work to achieve them.
5. Let them know if you need something. Take care of your own wants.
6. Seriously, don't cause their phone to ring, or through inaction, allow their phone to ring.
