When we concentrate our attention on specific issues, whether they be goals, problems or people, we bring all our energies to them and shut out the irrelevant noise.
Be careful not to attach your sense of fulfillment too tightly to specific outcomes and circumstances. For there are far more possibilities than you may have yet imagined.
We are at our best when we are moving toward a meaningful, positive and ambitious goal. As each goal is reached, we need to use the position we've attained to stretch even higher.
