The best manager I've ever had motivated me by providing me space to work on my own and acknowledge my good work while also coaching me in areas that I needed help in instead of talking down to me or berating me. This method worked because it felt like my manager trusted me to do my job. It helped me feel independent and feel responsible for my role and my position while not being micromanaged, but it also made him approachable for when I did need help or if I did need coaching or if there was something I was struggling with. I knew that he trusted me to do my job, but I could always reach out to him if I needed anything.
