I discovered this list online taken from the memoir of the ex-US Secretary of State Colin Powell. It is a useful practical listing of leadership advice.
It ain’t as bad as you think. It will look better in the morning.
Get mad, then get over it.
Avoid your ego being so close to your position that when your position falls, your ego goes with it.
It can be done.
Be careful whom you choose.
Don’t let adverse facts stand in the way of a good decision.
You can’t make someone else’s decisions.
You shouldn’t let someone else make yours.
Check small things.
Remain calm. Be kind.
Have a vision. Be demanding.
Don’t take counsel of your fears or naysayers.
Perpetual optimism is a force multiplier.
