There is a rather frustrating and a long-time process into making money, but this way the money is sure. Most people believe that this process is worth the effort, since most people are doing this.
Step 1: Get a good education (there are different kind of educations, some pay better, some pay worse, with no education you are most likely going to get least money)
Step 2: Get a job. (This process might take some time)
Step 3: When you get a job, do the job right.
Step 4: Get money every month!
It highly depends on your education and your job that how much you are going to make. The profits can be anything from $400 to millions of dollars per month.
