Any advice for software developers that are in a rut? Basically, I have been working my first post-college job the last 3.5 years or so, but honestly what I do is pretty basic web app stuff.

I really want to get into a job where I have a lot more responsibility and more interesting work, but I feel like I have shot myself in the foot by working at such an easy (but decent paying) job for so long.

I am very interested in pretty much all programming related topics and study them for fun, but having not built any super awesome software makes me feel inadequate.

Honestly, I should probably just apply to some places and see if I can get a better job, but for some reason I am afraid I will just get turned down.
