Happiness consists not in what we have but on what we enjoy. There are things that we can only understand with time. Time is the best cure to heal the wounds of the heart.
Little details make the difference.
Never loose faith in God nor in yourself, since the greatest tests prepare us for the greatest successes. It's never too late to recognize our mistakes, to learn and start all over again. The ilusion that personal gains come from stepping on the others. The tendency to worry about the things that can't be changed or corrected. Insisting on the impossible simply because we can not reach it.
