Doubt, Fear, Guilt, Worry.

Doubt, fear, guilt, worry. 

Sometimes you think it would be better to live without these things.  Clear your mind. Drop the baggage. Live clean.

But then again maybe they are useful tools. Tools that must be used wisely. It's all about proportion and balance.

Clear skies, cloudy skies.  Each has their benefits and positive attributes. So guilt can be useful. Worry, fear, doubt too...
