If you just started your website you'll likely not have too many website visitors and in turn you won't likely make any money at the start of your website.
Making money from a website takes time and patience. Without much website traffic you won't make much money from your website in the beginning.
It takes time to build up website traffic as well. Don't expect a lot of website traffic in the beginning unless you have lots of money for advertising or are very lucky.
You should expect to work on your website for at least 2 years before seeing any money at all and then you'll likely be waiting until your website has been online for 5 years or more before you can see a monthly payout through Adsense or other ad networks.
Don't expect to make a full time living from your website in just a few years.
The bloggers that make a full time income from their blogs have been blogging for 10 years or more.
