If patience is a virtue, Google Adsense is a great virtue trainer.

I put up a site with the measly, puny intent of placing some Google Adsense code here and there.  Nothing much.  It took me two and a half day (well, working days) to get the right ads to show on the right pages.  

Result: my patience muscle has been significantly exercised.  It is, therefore, significantly stronger.

Bring it on Google Adsense!
