When you use the words "I can't" you have already preordained yourself to that destiny. Oh sure there are times when you push past those words, "I can't" and try something and not make it. But at least you tried and did not set yourself up right from the beginning to fail with the words "I can't". And there are even sayings out there that help you believe those words "I can't". Sayings like oh I don't know let's say sayings like: "Dogs can't climb tress. Cats climb trees, not dogs."
Hummmmm. Dogs can't what? I believed I could. I did not let "Can't" stand in my way. I didn't let "Can't" determine what I can and can't do.
Incase you have not guessed, this applies to oh so much more than a dog climbing a tree.
PS from my momma: Buddy is about 15 to 18 feet up a tree. He climbed up there all by himself.
