 Everyone hopes to live a long life. But how can you make your long life happy and meaningful? You can read on to find answers.
小题1:Go traveling wherever you want and go to see one part of the world you’ve never seen before. You will not regret it. Traveling has less to do with seeing things, as it does with experiencing them. It has less to do with discovering something, as it does with discovering yourself. You run into all the good things and bad things about yourself on a daily basis if you travel to new places, and you are provided with the opportunity to grow far beyond your years.
小题2:You can go through life and make new friends anytime, but no one can take the place of those persons who truly improve you. They are the most important people you will ever meet because they tear down the invisible walls you have built in your mind. In other words, they come into your life and help you develop your potential that you would never have been aware of without them.
小题3:The road to greatness is far from easy. You can be absolutely certain that when you feel you are getting weaker from struggle, you are in fact growing stronger than you ever have been before. The more difficulties you meet and solve on your lifelong journey, the more meaningful your life story will be.
小题4:One of the great secrets of happiness is freedom, and the secret of freedom is doing the best you can with what it done to you. It’s all about how you choose to respond to different situations. This simple choice makes a world of difference. If you find your situations tolerable, by all means tolerate them; if you find them intolerable, break through them. Eventually you are free because you alone are responsible for your thoughts and how you use them to improve your growth.
小题5:The best way to get ahead in this world is not to complete with others, but to serve them. If you want to get a promotion at work, be good to your boss. If you want to build a successful business, be of service to your potential customers. Provide unmistakable value. Value is what makes relationships, businesses, and personal efforts grow. At any age, in any situation, for every possible life path, there is value you can provide. Success and happiness will come when you choose to work for the world.
