Now that's someone thats never done a wedding.

"On the job" at a wedding is the LAST place you need to be learning and experimenting! If you are, you are fooling yourself that you know something, when in fact, the truth is very likely 180 degrees the other way.
I am not saying that people cannot learn while doing a wedding, but constantly shooting and experimenting is not a sign of experience nor ability either.
I know a guy that is in good health, reasonably good shape that spends 2 hours a day, 4 days a week on the driving range with a pro instructor. He spends on average $200/week on this, EVERY week! His clubs are custom made and cost him $19,000. ... yet he would give his right arm to be able to drive a ball past the 350 foot marker.
Sometimes, no matter how much time you spend doing something, you still will suck at it, even if you are guided by an experienced teacher. Now mucking along yourself, you are for all intents and purposes blindly seeking a path to improvement and some poeple won't find that path either.
Matter of fact, 90% won't get past a certain point becuase they will be so busy chasing their tails, that advance will be basically an exercise in frustration. They either eventually give up or continue to go in circles.
There are also a few that will try to fool themselves that they are something special... but trust me, they aren't.
There are very very few truly gifted photographers around... much less the additional higher challenge of being a wedding photographer.
