I think I need to keep myself working hard Recently I think I am not doing well with my plan. In this summer holiday, I want to do many things and had done a plan to help me carry it well. for example recite fifty words every morning and review them before sleep. learn Linear algebra through website,done a plan either. However,none of them I done follow the plan. so,I feel terrible now and a little bit of narrow. I know it is useless to worry it. I should exercise the power of execution. To do the plan in detail. To sum up every evening. To supervise myself through internal and external forces. Therefore,I decide to write the plan in some information platform. I wish to be better.
