"You become effective by being selective. We're like gyroscopes, spinning around at a frantic pace but not getting anywhere. Without a clear purpose you keep changing directions, jobs, relationships, churches, etc, hoping each change will settle the confusion or fill the emptiness in your heart. You think "This time it will be different", but it doesn't solve your real problem -- lack of focus.
...Nothing is as potent as a focused life. The men and women who make the greatest difference in life are the most focused... So if you want your life to have impact, focus it! Stop dabbling. Stop trying to do it all. Do less. Turn away from even good activities, and do only that which matters most. Never confuse activity with productivity... The first law of success in this day when so many things are clamoring for attention is concentration--to bend our energies to one point and to go directly to that point, looking neither to the right nor the left. Does focus come easily or naturally? No. It's a discipline that must be practiced every day."
