As to methods there may be a million and then some, but principles are few.
The man who grasps principles can successfully select his own methods.
The man who tries methods, ignoring principles, is sure to have trouble.
Ralph Waldo Emerson, American Author & Philosopher, (1803 1882)
While it can be more difficult to see initially, there is only one area of your life over which you have full control yourself. There are a number of discoveries about working with myself that have had a marked impact on my effectiveness:
Leverage Your Superpower
Focus on your area of greatest impact, not your area of greatest effort. Ask people who have worked with you where that is, as they can generally see it more clearly than you can.
Work the Toolbox
Everyone has a 'toolbox' full of experience, but only some of us actively use all that we have. Take inventory of your toolbox from time to time. It's amazing what you can find hidden in there.
Lead Regardless of Whether You Own a Team
I've heard people say that they'd like to be in a 'leadership role', but what they don't realize is that everyone already is (and it has nothing to do with how many people report to you).
Remember That Urgency is Not a Deliverable
Having an appropriate sense of urgency helps prioritize your tasks, but don't confuse urgency with delivery. Both are important, but only one of them has value on its own.
