7 things that Good Engineers DON'T do

1. Stop asking questions or looking for help. We can't possibly know it all, nor can we have solutions to every single problem a contractor may throw at us. Therefore the opinions of other experienced engineers [and graduates] will be a constant source of new ideas and confidence for us all.
2. Cannot admit when they are wrong. Much like the previous point, as we mature and gain experienced, some of us will find it very difficult to accept another persons point of view, or design opinions. Even if it is more suitable than our own. Admitting we are wrong can be very humbling, and it helps us build a more trusting relationship with those who seek to help us.
