Very true. Everything is there in the perspective with which we look at things. Every situation and every person has something to teach us - something we can do or something we have to avoid ... Problems and crises are the opportunities when we realise our own potential.

Mistake is miss and take...If you Miss doing right, learn from the situation and Take the lesson and add it to your life resume as a new acquired experience. 

Most of the time, students fully master a lesson after they answer wrong in an assignment. Their previous mistakes prepare them to take coming exams successfully.
