I have been the gc for my flips as well and trust me those skills you have are needed! 

I have discovered in the past few years the most valuable skill is the ability to find a deal.

I think applying your existing skills and experience is some times one of the easier ways to get involved in the Chicago real estate game!

I loved your points on sharpening your skills through education, making educated decisions through correctly running numbers on both renos/investments, and then your suggestions for the future landscape.

Another valuable skill to learn is how to find off-market or deeply discounted properties.  

I got a sales guy who had little clue how long or what skills were needed to do the jobs he was quoting me for.

I  would always suggest a Mentor and top notch Realtor with construction experience or contractor with Real Estate knowledge Mentor Never read a book on my skills. 

From a content perspective, the original book was written back in 2012/2013, when most markets were buyer's markets -- house flippers needed to be more skilled at selling property than at buying property, as buying was easy. 

Being able to pull the trigger once the numbers make sense is a skill and being indecisive will be a big hindrance on growing...I personally won't work with clients that are gun shy on pulling the trigger.
