Being a photographer
For years, my late father told me I was a good photographer - a great compliment - as in his eyes I could not do anything.
At one time I did think about becoming a photographer, I even started a course. The problem is to become successful you need to find somewhere that has no photograher.
As most villages have a regular photographer, you are required to set up shop for five years to attempt to establish your business, the next five years are for you to break even - if possible - only then can you consider making your work pay.
In the meantime, what are you living off for the first ten years?
