This really depends on IF you are adding in an additional revenue stream, or just modifying an existing one. Or if you're doing a combination or both. The average student has taken 2-3 months to actually start earning money because they need to upgrade an existing offer in their business, or create a new one - which takes time other than what they've invested into the class. While results are not instant in this class, they are likely to be permanent. Once you've done the work to up-level yourself and your business you'll continue to make money consistently.
And if you've used the course to help you set up a passive revenue stream as a part of your overall business strategy, you'll continue to make money even when you're not at work!
