Setting goals - do it in steps
A better way to set your goals is to day it on a step-by-step basis.
You should first set your target of making $100. Once you achieve that goal, set your next goal to make $500. As you continue to build you can increase your targets until you hit your figure.
This type of goal setting doesn't just relate to income. You can use it to determine the number of websites you create, the number of affiliate programs you promote, the number of blog posts you make etc etc etc.
Try it out, I know from my experience it helps out immensely.
