We cannot control everything in our life

There are things and matters in our life that are beyond our control.. the people we meet, the things we do and outcome.. The people we meet.. it comes and goes.. we cannot control the appearance sequence.. i wondered why not earlier.. 只是过客吗？。。does the outcome really matters or I just want the process.. The struggle within is unbearable at times and it's real.. now i truly understand the meaning of 进一步没资格，退一步舍不得。。
