7k in two weeks is very decent. If you can make this consistent and try to upscale even further while maximizing your profitibability its looking to be a good year for you.
I would always recommend to keep on testing and optimizing, even when you're winning big money at the moment. Campaigns eventually die out so you have to extend the life span of the campaign as long as possible by continously testing, optimizing and tweaking.
Also split-test networks against each other. This will not only spread your financial risk in case of non-payment (for whatever reason), but you'll also see performance differences and see if the network is scrubbing. You'd be amazed to see the difference in CTR and CR one the same offer by just running it with 2-3 networks.
