How should we hold the right attitude towards life

We donot need to think so much somtimes. Maybe life is short and precious, you should not make it sink in the worries and complaints. We need to be simple not only towards ourselves but also towards the life itself. Living in the world, we are all busy pursuing money, houses, fames. We seldom know what we really be lack of. We have no time to think about it. We even have got used to that kind of life as everyone seems to be persistent about that kind of life. Everyone are living upon that principle. They finally may have nothing left and donnot get anything they really want. We living on the earth just for enjoying the life. We may can take a piece of time to think about what we want in our inner mind.
