your keywords are probably too broad like sean said (9,690,000 hits for internet marketing course), but also, if you use the same display URL than another ad you will have to outbid them to get your ad shown.
google will NEVER show 2 ads with the same display url.
if you go to your adgroup and move the cursor over the little magnifier picture next to your keyword, they will tell you if somebody using the same display url has a higher ranking.. in that case you will have to outbid him
this outbidding can be expensive.. I have 1 ad running on 2nd place for 60 cents, another on 1st place costs me almost $1, and some I tried didn't even work on a monster bid of $5! in that case it's better to make a landing page
google's display url rule does come in handy for the outbidding though.
if I don't see my ad, I increase my bid a little, wait 2 minutes & check
if I see my ad on http://www.google.com/search?q=+&adtest=on
if not I repeat this untill my ad appears (unless the price is getting insane)..
