However, even though it is great for quick money, the only way to make it sustainable is to create a business and hire employee's or VA's, so that the business operates independently.

I feel the need to not just create a successful and sustainable life for myself but put my children in a position to own something that generates a source of income outside of their main subjects of interest.

@Danielle Wolter, your response resonated with me as I am currently "stuck" in a well-paying soul-sucking job with very little time to do my "passion" job.

Your goals resonate with me because they are similar to mine.

Change your story each month as different stories will resonate with different people AND use each story to emphasize one of your “who do you know…” questions.

I’m figuring it out just like everybody else but remember whatever business that you pick - you have to think about the ability to sustain it.

At the moment, I put aside about 40-60k in start up capital to start this new venture and I am wondering if that is actually enough to make this a viable business that can sustain my life and pay all my bills?

It's not sustainable past a certain point, and when I get there my business model will change, but by then I'm sure I'll have hit my modest financial goals anyway.

A more precise way to word this would be that a primary residence does not generate cash flow upon which one can sustain early financial freedom. 

Any and all marketing is about credibility, and resonating with your audience.
