Let me also suggest that the more you succeed in becoming an effective leader, the greater will be the number of the people who are your adversaries. Jealousy is a terrible thing to encounter. Many times you will have people seeking to attack you and your team. They will seek to work in a sneaky, underhanded fashion. Many are the landmines you will encounter as you work to become a better leader. That's just the way it is. Suck it up and move forward for the best interests of you unit.
There is no 'one-best way' to become a better leader. Each and every day you need to be there for your team. Help them solve their problems and support them as they seek to become the best fire people possible. Drill with them and give them wise counsel as you handle the whole range of emergency operations to which your people and you are called.
After these calls, lead your people in a solid critique of your efforts. Ask each person how they feel about what was done. Ask for suggestions as to how things can become better. Then be sure to incorporate the suggestions of your people into your unit's periodic training sessions. Here is your motto:
In this way you will be able to get better. Do not just blindly keep doing the same old things in the same old way.
