This quote has so much truth to it. The theory that connects to it is the Problem Based Learning Theory developed at McMaster University in Canada. This theory states how students can deal with problems that they come across in their learning. We will all make mistakes and have problems with our learning. It is how we overcome our mistakes that eventually will make us masters of learning.
