I am so called self taught developer.I learned how to write software out of boredom at work. Subsequently,I wrote some parts of the system,my current employer uses,that range from 'nice to have' all the way to 'mission critical'. I allowed myself a lot of freedom in terms of errors, mistakes and etc. The company provides training to people,so the worst that can happen is someone may not get a correct email or internal user won't see an update on training they were expecting.Now if I were working for Boeing and had to write code that'd go into production,aka a working plane,I'd probably either say I couldn't do it or do so many iterations that they'd would sack me...I couldn't sleep for the rest of the life knowing that I pushed some update that ultimately controls some parts of the plane and that it can go wrong any time...
