IMHO, the government should hire a mix of people. The "amateurs" can be trained by "professionals" like yourself, and the results are usually good for everybody.
None of us were "professionals" when we started our careers.
As far as "getting over myself" goes - why? I have done an exceptional job of serving my country (including losing part of my right leg to a machinegun bullet) and I have done really great things to keep our country ahead of the world technologically. There are certainly many, many others that have done the same but I don't see any reason at all to hide my own light under a bushel basket.
Like many others, I didn't get a parade when I got back from Vietnam - quite the opposite, really. Now I am my own parade.
