how do you simply make money with your blog?

I have also found it really hard to make money by blogging. I wish i could get more traffic to my blog so I try posting my blog every place I can. I also make my blog useful to others hopping they will return to my blog all the time. My blog is how I make money online and all the programs I use to make that money! Here is the link to my blog if you want to check it out yourself... you never know you might find something you want to sign up for and make some extra cash!
