[(Noob Question] Why isn't AdWords working for me?

long story short, i bought a google adwords voucher and loaded it up onto my account (which is a new account). I made an ad for my site, and picked a shit load of keywords for the campaign.

its been a couple days now...and not a single click. What gives? am i doing something wrong? any info would be appreciated. thanks!

Need a little more info. Have you looked to check if the ads are running for your keywords? I know sometimes on my new campaigns the ads are running but at the bottom or not showing every time I do a refresh because my bids are to low.
