Awesome! There's a first for everything and that first sale sure does feel good! I remember when that happened to me, that first $1.28 commission, felt like I was rich! So happy for you...now just keep at, keep duplicating your efforts in whatever you're doing!
Congratulations! Keep your positive momentum going by duplicating your current efforts. However, remember that internet marketing is about growing as well. Continue to research and learn new methods and techniques that may help you to refine your current efforts for better results. When you make a change, split test it with your current method. This means to continue using your current method, but implement your new method parallel to your old method to see which one prevails. This will allow you to measure how much greater your results are, and assess whether spending the extra effort (if there is any) is worth the increased earnings that you're seeing. Split testing takes time to learn, and the more that you do it the better you'll become. Just remember this... a good internet marketer who can accurately implement and assess proper split testing, will blow past another internet marketer with years of more experience who cannot.
