Sometimes I suddenly feel like a fraud, especially when I realize I'm in a meeting where everyone in the room has a CS degree or higher, but overall I feel like I bring a lot of value to what we do and most of all, I really love doing it.
I remember anonymously asking on Quora if people thought I was too old to learn how to program. The amount of support and stories that were shared with me were positively overwhelming. Probably the best answer I received was, "do you enjoy doing this thing?, if so, the answer is you should just do it."
