That type of earth-shattering failure and pain really does a number on a person. Getting clean and overcoming those demons isn't as simple as people make it out to be. You need to have some serious deep-down reasons on why you must succeed at all costs. You have to be able to extricate yourself from the shackles of bad habits that have consumed you during your entire life. And that's precisely what Sharpe did.
Black hat SEO is to be avoided. This is basically link spamming. You can pay somebody peanuts to do this on your behalf and, for a very short period, it brings results. Then Google sees what’s happened, and they delist your site permanently from search engine rankings. Now, you need a new website and new content, etc.—so, black hat SEO is a terrible idea.
Just think about any relationship for a moment. How long you've known a person is incredibly important. It's not the be-all-end-all, but it is fundamental to trust. If you've known someone for years and years and other people that you know who you already trust can vouch for that person, then you're far more likely to trust them, right? But if you've just met someone, and haven't really vetted them so to speak, how can you possibly trust them?
