I see this quote in many guises, but I quite like how Picasso has put it.

There was one in the gym I used to be a member of, asking if you expected different results from always doing the a same thing. I have in the past posted one about magic happening outside your comfort zone, but this one directly connects with me. 

Here, Picasso boldly states how we should always do things we cannot do. That means that when you begin, you will know its hard, you will find uncertainty, you may even doubt you can complete it.

But how will you know, unless you do it?

Everything we do in life is born out of learning and practice. You were not born knowing the skills that you know now.

Therefore, isn’t it possible that you just might achieve the impossible? After all, you have been doing it all your life!
