Welcome to the forum 19Norway!
To help you find your fursona one thing I recommend is think of all your personality's. What makes you, YOU!
And after you have some defining traits of yourself, look at the animal world. Which species catches your eye and from what you can tell, BEST represents the traits you have. Like a dog would represent loyalty, a dragon could be power, and a cat could be shyness.
It can all be looked at in MANY different ways.
Once you have your fursona species, All you need is a look, Witch is pretty straight forward.
And if you find it too hard to make just one fursona you can allways have multiple ones, Many others people do.
If you have any others question you can feel free to send me a PM.
