Realist,
Welcome aboard! As you can see, if we all agreed with each other here, all but one of us would be unnecessary. 
But seriously, this is a good group of people, quite willing to help those sincerely interested in learning. Don’t feel uncomfortable if you don’t have a lot to share initially. Read, learn, contribute when you can. You’re among some very decent people here.
