Spend your Time on Content

"Don't think too much about AdSense. Don't spend too much time on it. Implement some changes now and then, then relax and forget about it for a while - follow up on changes a few weeks or a month later. Don't spend your time constantly tweaking and changing stuff, that will get you nowhere. If you absolutely need to do something, spend your time adding content or updating your existing content in stead." claus
