How to Stay Technical While Still Managing People and Resources in Your Team

How do you stay technical while still trying to manage people and resources in your team yeah it's hard honestly i find every year that i continue to manage people i probably forget everything i know but i mean to be honest actually teaching helps me a lot because when i teach on the side i'm constantly reviewing things i already know and just constantly refreshing my knowledge. One of the hardest things i do believe as well is just the technology is changing so quickly  and it is really difficult to keep track of everything that's coming out.
