Today, while I was reading a book, I came upon this ridiculously long word. floccinaucinihilipilification This word means to estimate something as worthless. I do this a lot to myself, and I couldn't believe there was specific term for it.

However, why do I estimate myself as worthless?

I always base my self-worth on what I accomplish. I haven't accomplished much in my life. In fact, I have failed numerous times. How does failure strengthen me? I feel like it is destroying me.
