What type of manager brings out the best in you?

"I'm really grateful to have had great managers throughout my career, but my most recent manager stands out as the best. She always knew exactly what each of her employees was working on, but she was never guilty of micro-managing. I always felt empowered to do my work but also ask for help or feedback if I felt stuck. Her enthusiasm for the work was contagious; if a coworker was having a bad day, she always had a kind work or positive spin on the situation that turned the energy around. She's the exact kind of person I love working for."
