The ability to use the debugger for troubleshooting any unfamiliar code has drastically increased my confidence. Unfortunately I was not taught to use such tools while at university where we used to code on a daily basis. Also, using state of the art IDEs to be able to navigate between my own and third-party code removed pretty much all of my anxiety when dealing with code in general.
