I have a mixture of all the the answers previously but the bottom line is the best growth strategy is to implement a growth process. As Sean Ellis said, "No individual growth hacker or even a growth team can outperform a company where everyone is mobilized to accelerate growth." One opinion and one action won't create growth, it is rather a mixture of first analyzing and testing EVERYTHING. Qualitative AND Quantitative questions.

You can take a free growth assessment here https://www.growthswell.com/#assessment To find out what level you are at and then it will tell you where you need to focus first based on your answers.
