Hi Brad,
At Brightspark (www.brightspark.com), we are VC's and entrepreneurs. We divide our time between managing 2 VC funds and operating 3-4 startups directly.
The biggest lesson I have learned isthat being a VC is all about money - even in early and seed stage. Being an entrepreneur is all about strategic decisions and prioritizing effort.
I used to think that VCs were much more influential on non-financial activities until I went back to being a hands-on entrepreneur again.
