How do I be an effective general contractor?

[Nick Grewe]

I am based out of Wisconsin and have recently started to invest into realestate. Seeing as how I have background in construction, I obtained my pre-dwelling contractor license and am looking to get fully licensed in a few years to work on bigger projects. I am asking the BP community on what they think or wish every general contractor would do or know. What are some things or practices that I should have in order to be that 5-star contractor?
