Stick with what you know? I think not!

Everywhere you go you always get people telling you to "stick to what you know" however, this is something that I totally disagree with.
There is two sides of my opinion on this certain phrase; I agree that if you know how to do something and you are comfortable with it then yeah definitely keep on doing it. But there is a big world out there and if you only "stick to what you know" how are you supposed to experience new things? try new things? the answer is simple you can't.
 How do you know there is not something out there, something you never even knew existed which you could be really amazing at? the answer is simple you don't.

It's great doing something you know, but there could be something so much better out there for you, all you need to do is go after it, even if it doesn't work out for you at least you have tried, that's all you bloody can do!
get of your bubble/comfort zone and go looking for something new, make it an adventure with the result being finding something new, something that you love so much more than your original something which you knew.
