Nothing worth doing is easy and this also applies to and se and quite frankly any of the Google tools in use today.
Adsense is not for the faint hearted but when you get it right, it works well, however, you do need a good traffic stream, good content and an understanding of ad sizes, colours, placement (all of which you can easily learn on the web, it find a pro to help you).
If you want to try your hand with Adsense I see no reason why you shouldn't have a go but read some good articles first and then concentrate on your traffic, keyword selections and ad sizes, colour and placement, try and blend them as much as you can and just keep working in traffic, aim at 1000 visitors per day and you could start to see some return.
Good luck
