Here's something you probably didn't know. There is an entire industry of people buying and selling established websites, and buying and selling domain names for websites.  Think about it. An already built website with customers going to it. You don't have to build it , or think about creating it, somebody has already done that. If you get websites, build up the traffic to them, you can sell them for a profit. The same goes for domain names. get lucky, but a name before somebody needs it, then sell it when it is needed, or use it to generate your own website then sell the site.

Remember start small and work your way up. Always do your research first.
