As a leader, what are the most important things you’ve learned? What were “AHA” moments to that helped positively change the way you lead?

I was thinking about it today after a talk with a soldier about difficulties in his life. It got me feeling like I want to do more and get more involved. I already feel like I’m a pretty involved leader. My soldiers have told me specifically that I’m “one of the few leaders they can trust” and make them feel like I care. At first I was flattered, but the more I thought about it I felt disappointed because I’ve identified issues with other leaders within my troop and unit and fully understand why they feel that way. It’s kind of sad that they think I’m one of the only leaders they can turn to. I’ve confronted a few leaders tactfully to have a conversation to try and help encourage them to be more involved and invested, even bringing up ideas to improve moral and get the soldiers more involved as a team collectively (most are above or the same rank as myself). Every idea I have seems to fall on uncaring ears. I’ve come to a conclusion that overall, there may be small change with these leaders, but they won’t full change they way they lead or the way they think. Now, I’m not saying these are bad leaders by any means. They’re incredibly proficient and knowledgeable. I’ve been strongly mentored And influenced by these leaders. Sometimes though it feels as though they have little investment in the soldiers and only develop soldiers as much as they need to, usually when the soldier messes up. They tend to have as little involvement as possible. Now, of course we have team leaders and section leaders to develop and push down information to the soldiers, but the level of distance is.....different. Instead of trying to continue to change others mentalities, I want to push myself to do more and be able to take some ideas and implement them in a way that will help increase morale, build some common ground and the feeling of a cohesive team. Any thoughts and insights would be appreciated!
