Hi Grey,
You are doing the most important thing: Riding. Do what works for you. I know it is hard when others are talking and you are not following -- I had that experience recently at a club event when folks were talking about their powertaps and coaches and all, I felt like I don't have money for any of that stuff and can't follow what they were saying. But what I realized is that I don't need that to ride and train and do my best and it helps if I don't compare myself to others (albeit hard at times). I am glad you are here and posting.
Cheers,
