When a leader improves

I am a lid on the potential of the people who serve with me. As their leader I can hold them back or I can choose to expand and grow so that those around me expand and grow.

I think it is tempting to want to blame the followers or those in less significant positions for the lack of movement forward in any given organization.

David is a guy who lifted the lid of leadership. When all (including Saul) were afraid to jump into the fight and take on the behemoth Goliath, David went for it and released the potential of Israel's armies:

Then the men of Israel and Judah gave a great shout of triumph and rushed after the Philistines, chasing them as far as Gath and the gates of Ekron. The bodies of the dead and wounded Philistines were strewn all along the road...

I have to ask myself - where do I hold the armies back? in what way are my own limits, fears or inadequacies holding us back from exploding in fruit?

What lids can I lift? How can I improve today as a leader?

Any suggestions? I am open...
