Below are comments you've made in this thread. Any one of them could serve as a case for you not taking paid work yet. Together, they certainly do speak for themselves.
What you do have going for you, though, is the fact that you realize you have shortcomings and are seeking out advice. A lot of people, sadly, simply decide they've got what it takes, hang out a shingle and open up shop.
I just did my first wedding...
I feel like I am just being to cautious and not putting myself out there for payed work.
It was my first wedding...
Also I lack a lot in terms of what to shoot...
I guess I need to look more at my books and learn more on what to shoot and how to set it up.
I am only one year into anything.
I knew that I was not up to par with a Pro wedding photographer.
I will be honest and say again that I know little about photographing people and was expressly nervous.
I feel like I need a lot more time on camera and need to get out of my comfort zone a lot more.
This is my view on shooting weddings: You need to nail it. Every. Single. Time. There's no room for error, and there's no room for nervousness or apprehension. You need to think on your feet and make the right choice every time. And, if you screw something up, the couple will hate you forever.
I've shot one wedding in my life, and I had the assistance of a guest who was a wedding coordinator (the bride's aunt) to help me with posing, etc. It went well, and the couple was extremely happy, but I have absolutely no desire to ever do it again...
