Meaning of Life == Happiness??
Had a long talk with bobo on the phone. Got some really interesting thought when I was giving my 'lecture'.
I always believe that the meaning of a person's life is his/her own happiness. No matter what you do, the final target is to make yourself happy. Different people find happiness from different ways, e.g. shopping, chatting with friends, being with loved ones, or working (less likely).
Also some people find happiness from being rich, having power / authority, seeing somebody else suffer, committing crimes, taking drugs. On the other hand, some good people find happiness from helping others, paying whatever price they need to pay, including sacrificing their comfortable life and live in rural villages in developing countries, to teach children, look after sick people.
People believe in God because they want comfort in their lives, and after their lives (I may have misunderstood the meaning of God, please leave comment to correct me). This in turns gives them happiness.
Happiness requires investment, often long-term investment. In the way of getting happiness, one may need to get through a lot of sadness, suffering, and doing something they don't enjoy. Working (as in 9-5 work) is a good example. People spend a lot of their time on doing something that they don't really enjoy (I bet many people would find being in a beach is more enjoyable than working in the office), in order to earn money to build their happiness by e.g. living in a comfortable flat, feeding their children + wife.
Therefore I think a person should not be afraid of little sadness, suffering, if they are part of the process of getting to eventual happy life. This may be obvious for a lot of people, but I believe the real meaning behind this is not obvious at all.
SEE FURTHER. INVEST WHEN NEEDED, IF YOU THINK IT GIVES YOU GOOD EVENTUALLY.
PS: of course, investments always have risks. For the above reason, you shouldn't be too unhappy if your investment didn't payoff. Your initiative was right.
