We need to constantly prod those around us to wakefulness by asking questions like "why did you chose this over that" or "what factors led to the decision to do that?" etc.   These should be internal questions too.  If no one is around to prod you, prod yourself.   If you need a poker to prod yourself, buy one.   Don't get lost in the codes, details, loads prior to looking at the full picture.  If you have trouble looking at the structure as a whole (or connection as a whole, weld as a whole), then you are not effectively managing your time.  You will have trouble seeing what you need to focus on.   You need to determine which areas of the project need special attention and which do not.   After all...

What we see depends mainly on what we look for.  [John Lubbock]
