Everything is decided on the way you put it.For example,you may have lost a critical and important chance,making you cry from the heart.However,if you think it the other way,like you may have a better chance next time,a smile would appear on you right away.So,having a positive point of view is incredibly important.That is because having a firm heart,intense dream would give you unresistible confidence,making you have hope and not give up.If you were thinking in negative ways,trouble and headaches would be something you would meet.单词量在多点，不够，谢谢这只是个大概，再加多点细节就够了哦，谢谢
