~Experience is the hardest teacher, it gives you the test first and then the lesson.~

~Be careful of your thoughts, for your thoughts become your words.
Be careful of your words, for your words become your actions.
Be careful of your actions, for your actions become your habits.
Be careful of your habits, for your habits become your character.
Be careful of your character, for your character becomes your destiny.~

~Don't let the past create the future, let the future erase the past.~
