In around 2008, I purchased the first domain called Qwerz.com which I bought to create an education portal teaching PHP, Web designing and other related technologies. I was a first year college student then and the memories is what I cherish now.
In matter of few months, I got hundreds of registrations then and I did upload many tutorials on it. Later on, thanks to my perpetual chase for shining balls, I switched to other projects and quite let it go.
Learning - if you are getting some success in your gig, pursue it more and exploit all opportunities. Make best use of your time and stick around for a long haul.
