If there was anyone doing the impossible it surely was M.C. Escher, my fellow countryman who excelled in creating impossible perspective and form morphing drawings. And I feel somewhat connected to him, since I perform the same warped operations on language instead.
The word impossible is a terrible inhibitor, unless you insert a quote and a space, in which case it becomes "I'm Possible". And yes, you are one of those things that could be deemed impossible, but isn't!
As Will Robinson said in Lost in Space:
"The impossible is only possible if you believe it is"
And I, as a decades older and hopefully wiser guy, agree with him. I've seen things happen that I thought were impossible, and the more I started to believe, the wilder the events went...
