What is life?

Ever since we got back home to Singapore, we have been leading the same life as most people. Wake up, go to work, back home, sleep.  Its really a routine that I don't really like.  I just don't understand why some people can be doing this for their whole life?  What satisfaction do they get from their life?  Is it a good paying job? nice car? big houses?  Surrounding you are peoples who are doing very well in their career, living the high life.  But when you examine their life carefully, you will notice that most of them are not emotionally happy.  They are only working for money.  I must admit that money really make the world go round, if I didn't have the money, then I wouldn't have the luxury on going this trip.  My thinking and mindset have really changed since the trip.  I understand and appreciate life more now.  Sometime its really depressing when you look at those poor people in turkey and egypt struggling to make end meet.  But 1 thing you can find in these people are that they are easily contented in their life.  They are living life day by day.  What is most important for them is having food to eat and a place to sleep.  Their life are filled with hard-hood but they still soldiered on.  These people are really resilient and great example of how we should live our life.
