Seek and you will find it

The world is wide and new to you. There are so many things to know. You don't have to know everything. You just have to know this: You are probably not the first one asking your question, or struggling with your problem. So google your question / your problem, and see what answers / solutions come up. Examples:
I want to make myself look thinner / fatter in a picture so I could sell biscuits better. Pinta won't do it for me. Perhaps photoshop, but that is not for Linux. GIMP is an alternative to Photoshop, but can I use it to mess with pictures and make people thin / fat? I asked google. Well, someone thought of it before (those who invented gimp first, but then someone explained how to do it). So I followed these steps and got this:

You want to use gimp but don't have it?
Google something like "install gimp ubuntu"
Then follow instructions.

Let's try something else.
Ahh, I have to think of something
