Be sure to keep your mentality, don't adopt the sales mentality where you just try to make as many sales as possible. If you're not making enough, maybe you should charge more for services, while at the same time improving the quality of work. In web design and programming, I always put quality above quantity. If you do a great job, your service will sell itself by word of mouth.
This is totally true, with one giant caveat: how much you are worth will not sell itself. You will get referrals, but you need to make sure that you are negotiating properly or you can wind up swamped with work that you aren't charging enough for. Sooo, even if you feel like you have all the work you need, you owe it to yourself to do some sales reading. ;-)
