Unexpected negative events are not rare in your life unless you are perfect. But, we all know that no one is perfect; regardless of the positive thoughts we pump in, we all have to face various consequences that can bother us.
It is true that we have no control over the events occur unexpectedly. However, as photographers who look at the world in a different manner, we have a chance of creating something artistic using the negative thoughts. As a professional photographer, you can convert your thoughts into photographs. You can look around with an eye of a real photographer to find scenery that suits and expresses your negative thoughts such as loneliness, pain, sadness, pressure, anger etc.
Who knows; what you capture to express the emotions can be a masterpiece!
