Find a better place to work. Just started as a software engineer, fresh out of college. I come home and I am constantly learning, which I enjoy, go to work and introduce new ideas and am shot idea not because of my ideas but beucasue im a newbie. Over the past couple of month has eatten away at my confidence and starting to just blow it off. :(
Yeah it sucks, but if you insist on the security of a larger company (my assumption), that's how it works.
