All of this while taking on my college courses while in high school. Right now, I'm probably in the negatives in terms of profit but the investment is neccessary for me to succeed. Sometimes you just have to trust in your gut, I suppose. Don't make a completely brash decisions but do have a bit of faith that you'll end up where you want to be.
Here's a Steve Jobs quote: Again, you can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.
Right now I'm focusing on one site, that same site that I mentioned. Since then the site has been jumping up and down google so sales haven't improved by much, but I'll tell you the truth - The most important thing I learned from Michael's coaching was the fact that I wasn't blindly building backlinks to no where but that they were all very necessary to improve. Though it is difficult to assess, especially in my position, I do think there is some improvement.
Unfortunately, I'm actually a HS student and I don't have much time to deal with this so I've been checking out backlink services to help my site out. Therefore, my link building hasn't been as constant as Michael would have recommended. Really, take what you can from the experience. Learn some lessons here and there and then make a plan. I plan to create sites like this, multiple, get a good constant revenue up, start flipping sites, start hiring ppl to make the entire sites for me and have an automated business going.
