This sort of goes along with my personal philosophy on success, which is some mixture of the following ingredients:
-Positive thinking and/or believing that whatever goal you’ve set can be accomplished
-Perseverance
-Creativity
-Laughter (or at least not taking yourself/work too seriously and stepping away from the computer occasionally to do something fun)
