I need all the advice I can get.

As a new Associate Project Manager I am reaching out to get some advice from my veterans in the game. I was on sales side of real estate and I was pretty good but building was my passion. I have helped a couple of my investors rehab a few of their properties but now I'll be in charge of the whole project. Any Project Managers have any advice for a newbie? I want to stay very efficient and impactful.
