When I first started coding I had a huge fear of breaking something as I got more experience and got more comfortable that fear went away, its always a little there but nothing to stop me. Now I struggle with the "beauty" of my code. Will people think that my code is ugly. I will add "Code Fearlessly" to my arsenal of things to repeat when I am scared...the other one I like is "there’s almost no code worse than no code." by Nathaniel Talbott.
