I wasn't sure if the grammar goes like "an good artist" or "a good artist"?.
But anyway.. (I'll fix it if it's wrong here).
Back to topic;
This stamp is to tell that you don't really need more than paper, eraser and a pencil to make art.
Some people run around and think "Omg I don't have photoshop/sai/copic ect. Then I can't make art". But the thing is even with with those tools, you still need some skills. It's not the tools alone that make the art, believe me. And you can do good things with simple things like paper, eraser and a pencil really.
So don't just sit and wait for getting some "fancy" equipment, grab a simple pencil and draw if that what you wish for XD.I personally started with fat crayons and paper as kid (jumped over to pencil eventually though). and later on digital I started with ballmouse and ms paint on windows 98 ..
