How to Simplify Your Life
Less is more. This is why we say: reduce things by half instead of doubling them, get rid of junk instead of piling it up, relax instead of stressing, slow down instead of speeding up. Apply these principles in your everyday life in a conscious way. You will then find yourself well along on your journey to simplification.
小题1:
When you concentrate on one task, you find you have energy that you didn't even know you had. Just imagine: you arc at a fair and you have to carry two heavy pigs over 100 yards. If you keep grabbing one and then the other, it will take forever, because one of them will keep slipping out from under your arm and running off. But if you tie one pig in a place, pick up the other, gather all your strength and make a dash for the finish line, pause for a moment, run bock and get the other one, and with great determination, carry the second pig to the finish line, then you can be sure of succcss.
小题2:

If you have the feeling that 24 hours per day are not enough for nil the things you need to do, then it’s not because the day has too few hours, but because you have too many activities. A simple fact that overloaded people often tend to forget. The solution is equally simple; refuse to accept so many work assignments in your private life or your working life.
小题3:
“I can handle stress” is regarded as a positive statement in the world of work. People who can handle stress are given more and more to cope with — until one day they break.
Pay careful attention to the signs that tell you that you arc under more stress than you can cope with. These signals came from various areas of life. You become ill, or your work efficiency decreases.
If you have any of these symptoms, change your life goals and decrease your tolerance of stress. Say quite openly, "I can't manage that. "
小题4:
"If only I were slimmer, more beautiful, richer, more clever, then I would be happier. " This is a dream that makes a lot of people ill, depressed, and unhappy. Life has its flaws, defects, comets, and edges. Only those who accept this reality can lead a really full life.
Of course there are activities in which errors are dangerous; driving a car, crossing the road. But life doesn't consist entirely of these things. In among them there is a lot of room for small and large mistakes.
小题5:
Successful people ail have their own places where they can withdraw in order to work. Find out which places improve your creativity. For me it's the train. When I know that I'm going to be traveling for four hours without phone calls and people knocking on my door, I find my mind is free and I can read or write complex articles. There can be problems working on the train, of course: if the person sitting opposite you keeps talking away, or if train trips make you tired (some people fall asleep after a few miles).
