From the beginning to the end. The standard response. Because you can either make nothing or a lot of money there (not infinitely much, of course, but look at those who founded Google, comment-367127 Amazon and other services).
But none of this matters because a common beginner mistake is to expect to see millions of dollars right away. This is not going to happen. Everyone begins with a small step (and Google and web page Amazon too). And you begin with small steps.
After all, the Internet’s best feature is that it allows you to increase your earnings by gaining experience and new knowledge. So to speak, everything is in one place.
