This is so true for beginning developers. They tend to have a mindset that once they run something and it appears to work, then that means they likely got it right. In reality the code might be right for 90% of use cases, but once you multiply this over a whole project, you end up with total dogsh*t, and mainly because of laziness too. This is the biggest reason the inexperienced developers create such horrendously buggy code.
