If you're in need of some quick money then Adsense isn't going to get you any quick money if you're just starting the website.
Making money from a website and adsense can take a few years at least. And to really start earning into the thousands of dollars per month mark could take a decade or more and it's not guaranteed.
To make money with adsense you need website traffic and lots of it.
For awhile you may not earn a cent but don't be discouraged. Adsense earnings take time. You'll need to focus on building your website, adding good unique content and work on the website traffic.
Then the money should follow.
If you need some quick cash you will have to find an offline job or take out a personal loan through your bank.
Adsense isn't a get rich quick scheme. But people can and do make lots of money with it. But it wasn't easy.
It took hard work in the beginning to get to where there earnings are.
