Rome wasn't built in a day nor will your business. Don't expect to know everything in a few days here, I have been at this 13 years now and I am still learning new stuff each and every day.

Focus on the training, take action on the tasks/lessons and don't worry about anything else at the moment. This is going to walk you through the exact process of creating a successful business online.

I understand how you felt! I agree with Jeffreys comment. Take it easy.

If its your passion, go with your niche. Any site can be profitable in time, but it takes good content to get people coming back to read your posts. Once you start gaining a lot of traffic to your site, that's when you monetize it with affiliate ads and get paid for your time. Sometimes it takes awhile. It could take a year. But if you had to pay for a marketing education that's very expensive? "Patience"
