Life just likes a runway, and there are countless challengers, when you speed up your step, you will exceed the front people; when you are tired, and stop the forward step, then perhaps the failure will be under your feet.People live with frustration, suffers, and challenges just like the shadow following you. If we hesitate on the road to success, and timid, then, no need to forward again, because you are doomed to fail, but if you go forward courageously, and never give up, believe the frustration, suffers, and challenges are your stepping stone, then, you will succeed in time.If we never want to challenge by ourself, then we will begin to doubt our ability. If we give up too easily, we will succeed on nothing. So, we must believe ourself and never give up. 请楼主检查。
