Five Secrets of Living Life to the Fullest
I believe that men and women through the ages who have led successful lives have captured these five secrets of living life to the fullest.
_____________This means having a deep sense of responsibility for your thoughts and actions. It means keeping your word, and being faithful to yourself, family and work. It means believing in what you do and working hard. It means setting your own internal standards, and not comparing yourself to others. It’s not a question of being better than someone else；respect and honesty demand that you be better than you thought you could be.
_____________ Believe in others, and take time to achieve their dreams. A wise man said, “If you want one year’s prosperity, grow grain. But if you want ten years’ prosperity, grow men and women.” You can build into the lives of your family, friends and colleagues by providing nutrients of gratitude and encouragement, and by investing your time and energy in their aspirations.
_____________ Individuals who live with abandon have discovered that personal trials make them more sensitive and loving, while building endurance and character. They have learned that achievements worth remembering are stained with the blood of diligence and etched (铭记) with the scars of disappointment. The pages of history are filled with the heroic stories of courageous men and women who triumphed over disabilities and adversities to demonstrate victorious spirits.
_____________ We live in a goal-oriented society that wants problems resolved now. We want three-minute oatmeal, one-hour dry cleaning, and instant success. But to live with abandon, we must live one day at a time, enjoying the little victories, realizing that life is an endless journey in self-discovery and personal fulfillment. It means taking time to hug your kids, kiss your spouse, and let the other fellow ahead of you on the freeway.
_____________ I do not believe you will live happily if you set out to live life for yourself alone. Choose a cause bigger than you are and work at it in a spirit of excellence. It will become a part of you as you see your goals through to the end. Measure success not by what you’ve done, but what you could do.
