Are frequently used to show yourself familiar with and good at things, so when people face the difficulties and challenges, the first thought is back, so lost much beyond their own opportunities, and can't play to their potential, this is very regrettable. In fact, people can overcome difficult things to make themselves progress, to do unexpected things. Brave people dare to challenge the impossible and succeed.

人，往往习惯于表现自己熟悉、擅长的东西，所以当人们面对困难和挑战时，首先想到的是退缩，因此失去了很多超越自己的机会，并且不能发挥自己的潜能，这是非常可惜的。其实人们战胜困难的事情会使自己进步，做出出乎意料的事情。勇敢的人敢于挑战不可能的事情，并且成功。
