There's a lot of advice you get from helpful people, whether on the Internet or elsewhere. This site, for example, is all about being helpful. We're here to help set you on your path to awesome, and give you tips to keeping it up. What you may find, though, is that the advice you get is entirely unhelpful. You'll read something about how to begin artisanally stippling Solo™ cups or somesuch, and you'll give it a try, and it just won't work for you at all.
The important thing to do at this point is not to presume that you are incapable of realizing your Solo™ Stipple dreams. And it's not necessarily a matter of practice, practice, practice, either. I mean, yeah, you're going to have to practice, but it's also entirely possible that whichever bit of advice you ran across is not quite right for you.
There's a scripting language called Perl, and unlike many of the programming languages that came before it, it was very flexible in how you could approach solving different problems. Because of this flexibility, especially compared to older programming languages, programmers new to Perl are given the handy acronym, TMTOWDI (pronounced tim TAU dee), which means, "There's More Than One Way to Do It."
TMTOWDI is a great thing to remember. Everyone's a little different, and some people are a lot different. There's no reason to assume that just because something works for one person, it will work for someone else. However, the great thing about the world we live in now is that you can probably find dozens or even hundreds of different ways to get you going in your Stipple Cup empire. Chances are, one of them is going to be the right approach for you. And, if it isn't, then you're probably going to see enough of the similarities and differences between the approaches to be able to figure out the rest on your own.
So give it a go and try it different ways until you find the one that works for you.
