Usually, when people around you hear you've become a team leader, section chief, or some kind of leader, they congratulate you. And, of course, you feel good about it. But from my own experience, I think there are also quite a lot of hardships that come with it. It's really not easy to maintain your leadership, achieve your goals, and look after your team members' mental well-being all at the same time. I believe that the team leader's main responsibilities boil down to two things: taking care of your team members, and taking care of yourself.
