The second (and cheaper) path assumes that you have the design and dev chops yourself to build your dream software. Naturally, it’ll take more time to get your product off the ground, but being able to bootstrap the development of your software lets you retain more ownership in your business and be more in control of your path, making this a lower-cost, but higher time investment to make money selling apps.
I DO know Wealthy Affiliates first-hand as I WAS a member for 1 year. I used 3 websites through them and I was successful BEHIND the scenes with networking and connecting with people but there I did not get the help I needed or wanted. It wasn’t like I did not reach out to others either but the worst part of being there is right now over a year later.
