If you're happy, you're already very successful my friend!
Nothing wrong with letting the site help pave the way with the free membership status "ALL THE TOOLS ARE THERE AND AVAILABLE" Make the most of it and you will be successful! SOunds to me, like you already are though, being happy. That said in your future success set more and more lofty goals and see them through like your current goal. Whatever feels good and right to you!
You have the right idea and so I want to share another perspective if you have a premium membership you have access to other tools and benefits that can help fund your site.
That's the beauty of WA, you can build and do exactly what you envision...
The question is, what do you envision?
Please do tell!
