1.
We all want to buy a new piece of electronic product, spend an expensive night in town, or take a loan for the good-looking care we can’t afford in order to make ourselves happy. You might feel great when you get those things, but later rash(轻率的) spending will hurt you a lot. Because expensive things don’t create lasting happiness and security. Careful spending will bring you great enjoyment in the future.
2.
Wise investing is also something everyone can work on to live happily. It even can make a big difference when they retire between their 40’s and their 60’s. For example, if a person in his early 20’s invests 20% of his ine in a fund(基金), the interest he earns will equal his current salary when he reaches his early 40’s. He could retire without a drop in ine!
3.
To be happy, we need continuous growth. The best way to grow is life-long education. This doesn’t mean you need to spend 2 hours reading every day. What you need is just to keep an open mind and search for fresh ideas. Education builds over time. You might think that the bits of wisdom you acquire every day don’t mean much, but over the years they will add up to make you a wiser person.
4.
The personal relationships we develop with friends and family members are the greatest source of happiness in our lives. Don’t forget them. Taking some time to build and enjoy personal relationships is essential to long-term happiness. No matter how successful you are, you’ll probably be miserable without the people you care about.
5.
If you always feel unhappy and think your life is terrible, try to set a goal which interests you a lot. We can’t control everything in our lives, but working towards a goal gives us something positive to focus on and lays the foundation for the future success.D
