It is in the nature of us human beings that whenever we do any hard work, our heart wants us to get the reward of our hard work immediately.
And often before we work we start thinking about rewards and even during hard work we only think about rewards or peace.
It is very important that we keep all our attention on our work during hard work because the better we work the more we can get a chance to get reward and the better the reward we get the better our nature will feel.
And it is also important that no matter how hard we work, we will not be rewarded accordingly, but keeping a good hope helps a person to maintain his hard work.
Often it is impossible to get a reward for the bad work done in distress because a person cannot do a good deed in distress so he is not even entitled to get a reward.
We know that anxiety is not good for us in any way but still we fall prey to it and in order to get rid of it we also need a reward that will bring us happiness and remove our anxiety. And as always, the reward comes only after hard work.
