In our daily life we can see our problems as giants, who stand in front of us showing all their power, often managing to frighten us, as we can see in the first image the building of mirrors very beautiful, I take it as a reference in the way we see many of our problems, I say thinking of my experiences lived when I found myself in front of many of them.
When you face them with courage and we decide to have determination, the change can be very noticeable, whatever the problem is, you have to fight even if the error has been our admitting it is a way to fight, always defend what does not seem right to us, everything like your beliefs, way of thinking.
In image two, it is how our problems are seen after overcoming them, in fact all of them are that size, but as long as we don't face them they will continue to look like the great Goliath.
