The leadership is slightly complex thing, so I wrote this ideas that I had left in the inkwell. For me a leader has to:
To know in what he invests the time: identify “his spendthrifts of time” of his team of work. Are you doing things that he does not need, like to go to unproductive meetings?
To focus in the contribution: he must asking himself: what can I do to affect of significant form the results of this organization?
To develop fortitude: his own and the his subordinates. If you work with the people, benefit from his fortitude instead of concentrating on his weaknesses or flaws.
To establish priorities: do the most important things first. Those who commit themselves with a long list of projects, and advance a little every day, they do not reach turned out in any.
To systematize the decision making:
a) define the problem in precise and finished way.
b) specify what the decision must achieve.
c) turn the decision into action (report what debit to do to him who it should do it).
d) prove the effectiveness of the decision obtaining feedback.

I agree with you that leadership is complex thing, but..
Very difficult to manage your time, when have multiple problems or tasks. So that, i think, you will lose your time while will be to define a problem and to specify the decision for every task.
