Last January, I attended the Domain Name conference NamesCon 2016 and learned a ton about domain name investing. If you haven't heard of this, it's actually really important for new entrepreneurs. You have own your domainname.com, since that is basically the equivalent to owning the land that you build your house on.
Additionally, if you can purchase your competitions land, you're going to have the upper hand (no I don't recommend investing in trademarked domains). Or if your competition owns your domain, you'll learn how to get it back (if possible) and not overpay.
One of the most common arguments when it comes to networking is that introverts struggle more than extroverts. This is not only false, but introverts have many qualities that actually make them more strategic networkers than extroverts!
