A is for Accountability: Knowing what comes in, what goes out, how it does and why. Accountability is arguably the first port of call for every leader. For some it's with resources, it may be money or even people. Whatever the case may be for you, take the responsibility to see that by your care and effort, you can account for them all.
Don't allow negligence rob you of the good you stand to gain. You can't take that risk in leadership, it's too costly.
