Hope is a powerful emotion, powerful enough to move whole cities from depression and in some cases poverty but this is about hope on a smaller scale, something like changing a mindset, pursuing an individual passion, effecting someone in a positive way even if at first it may seem arrogant.
Some people in this world are like water, transparent, colourless, dilute. These people are the hopeless, the ones who lack the fire of passion, drowned in self pity and narcissism. People of these qualities often do not understand the concept of creativity and therefore look down on people pursuing a creative passion and see it as a waste of time.
Self doubt also has the quality of water, it is a feeling that is at first shakeable, you can brush it off as a bad day and see further into the future. Then it happens, again and soon after that, it becomes a reoccurring thought you are forced to fight each day in order to maintain sanity.
The water soon fills our eyes with tears and over time transforms into a body of water immersed in negativity, this could has grown from one or a few antagonistic people and their doubtful comments into a pool of thoughts that have grown from your own mind.
The overwhelming idea of not being good enough.
