Well,in my opinion,whether you lose or gain something is depending/dependent on the will of God.
As you know,any result has two kinds of factors:subjective factors and external ones.The actions of people’s (man’s) efforts are the process of converting subjective factors into external ones (the course of creating conditions is the process of transforming what you think into the external factors).Only when all the external factors meet together,would the wish (would) become true.
However,some external factors are not the ones that can be determined by the efforts of people.So under this circumstance,what we can do is just to do our best,as to whether it can be realized or not dependent on the external factors that we cannot change,that is to say,depending on the will of God.There are too many results of (like) this kind in our daily life.Take the examinations as an example,if you got a bad (serious) appendicitis the day before the college entrance examination,no matter how much effort you took before,you have to wait for the next year’s exams.
Since we’ve know (known) the limitation (limit) of human beings,we should take the attitude of “Man proposes,God disposes”.Only in the way of taking the factors of God into consideration,(would) we would be less upset when we fail.So let us just keep a normal heart towards loses and gains in life.
