I don't feel qualified to apply for jobs in my degree?

You know, it is normal, average, the usual thing. Sometimes I feel the same way, and I have been working for 28 years. But then I see what other people are doing and hearing how people feel about it. The other people are getting good ratings and I am doing just as well. You just need experience. Sometimes you don't know what you can do until you do it. You will be fine. I like your humility.
