**Fault tolerance in both life and work** We live in a world which is easily get stressed when things does not follow a right way. Small or big things, in both life and work, those are almost inevitable. I never have seen a person is always doing the right thing and never making any mistakes. But some people I have seen is close to that point in every life and work decisions. The environment is something we can hardly control at most of times, coming with unexpected things, but ourselves are to some extent in certain under control. A self-discipline person is able able to make the room for fault and time to fix it, which does not have to end up with a stressed environment. Everyone who experienced that will know it is difficult to carry out time control, a well-organized schedule for when to work, when to stay with family, when to improve ourselves with body and knowledge.I see many people spent each day passively, however, if you have short goal or long goal in mind, when looking back, those life pieces are connected forming into the milestones one after another. For example, when living with family, you got plan ahead more things apart from the project goals, the conference presentations, the fund application deadlines, and the research ideas where they can bring you. Something like financing, investments, tax return, schooling, daycare, housing, jobs, medical conditions, etc. I am not as smart as foreseeing everything, but I can sense that everything will be OK. World peace !
