What existentialism taught me about life and photography

From the philosophers, Jean-Paul Sartre & Albert Camus I've found myself questioning everything in my life regarding existentialism and photography, passion, knowledge, devotion & skill over the past two years, soul searching if you will. What I've learned is there is no purpose or meaning to something unless you give it one. Essentially existentialists believe that an individual has and can control their own free will to choose and act. People make decisions based on what has meaning to them, rather than what is rational. What I mean by this is if your photography makes you happy, then it makes you happy because you give it value and purpose in your life, and that it is of your own free will that you give photography these values.
