How can I leverage who I know through my net network?

Your net network may connect you to hundreds or even thousands of people you've never met. Try, in as much as you can, to make sure your network shows people who are an asset to your construction career path. The more you know people others want to know, the more others want to know you. If your network contains high-quality, construction career-oriented people, it will grow organically in that direction and your prospects will improve.
