The triumph of the true man is born from the ashes of his mistakes; never ever complain of your loneliness or your luck. You have to face and accept it courageously!
In one way or another, they are the result of your actions and prove that you always have to win. Do not let your own failures embitter you, nor should you blame them on others. Accept them now or you will just be justifying yourself forever like a child. Remember that it is all right to give in at any moment. Do not forget that your present is a result of the past, in the same manner that the present affects your future.
Think less of your problems and more on your work; and your problems, without eliminating them, will disappear. Learn to be recover from the pain and to be greater than the "obstacles", because you make your own destiny. So, wake up, fight, move on, decide and you will succeed in life.
Never dwell on "fate", because fate is the excuse of those who fail.
