This post brought to my mind a writing by Carl Jung and is the following:

Those who learn nothing from the unpleasant facts of life force the cosmic consciousness to reproduce them as many times as necessary to learn what the drama of what happened teaches. What you deny subdues you; what you accept transforms you.

Of course this thought is very broad and can be analyzed from many points of view (mental, emotional, mystical) but what I want to highlight from it is that, faced with a situation that we consider has been adverse to us to achieve our purposes, we must analyze the cause that produced such a situation, accept it and learn from it so we can consider new strategies of life (or work) that allows us to achieve what we want. The question is that we must be conscious and responsible, assuming our decisions and not just blame the boss, the family or destiny.
