'Photography' is actually a highly varied discipline, whose requirements (of the the photography) are also highly varied!
The practice of these areas of photography, for example, are all quite different from each other in the skills and types of talent needed...
- medical photography
- family portraiture
- glamour & boudoir photography
- weddings/event photography
- sports photography
- theater/stage photography
- industrial photography
- product photography
There are skills and knowledge, there is artistry, and there is aptitude, all coming into play in different mixes.
Some are totally technical in content, with little 'creative' or 'artistic' (industrial, medical, newpaper photojounalism)
Some lighting skills are very different, depending upon subject matter (family portraiture vs glamor/boudoir vs. product photography vs. lighting automobiles)
Some require the ability to rapidly solve photographic problems 'on your feet' vs. less time demanding requirements (weddings vs. studio product photography)
Some call into play different aptitudes in the photographer
If I asked you to describe a 'successful business person', you would similarly describe a lot of different kinds of knowledge and skills and aptitudes, and occasionally artistry comes into play... a Wall Street tycoon is very different from a Silicon Valley genius or a Broadway stage producer.
you need to examine yourself and assess the breadth of your knowledge and skills, how artistic/creative you are (or not), and what your aptitudes are which can contribute to your greater success within ONE narrower field within the broad realm of 'photography'. And then fill in your identified personal gaps as necessary.
