How can you - confident leader or not - reasonably be expected to keep a whole team consistently engaged? A whole team. Of individuals.
In your hands lies a mixed bag of skills, backgrounds, interests and everything in between. Some have been with the company longer than you have and some started last week; it's your job to get them doing their best. Happily.
Inevitably, it's not always going to be an easy task. You may already know a couple of them and have common interests with a few others. There may be one you find more difficult than the rest put together, or one that intimidates you.
It can take time and effort, but the more you put in to creating a respectful and engaging environment, the higher the reward.
What NOT To Do
All of the above REEK of inconsistency and show a lack of confidence, which automatically warrants confusion and mistrust in disengaged employees.
Being an honest, personable leader is hard work, but it's addressing these underlying matters which will lead to committed employees who WANT to excel. It's completely possible to feel in control and respected at the same time as letting your guard down. If you lead from within your team with honesty, asking questions and engaging your employees on a more personal level, you will receive as much in return.
Steps to Success
Good leadership relies on attitudinal qualities, rather than simply management processes. Demonstrate the characteristics that will engage your employees to strive!
