Metaphor
When I see this image I relate it to all types of learning, learning to swim is time and technique and many times, hundreds of people do not succeed and sink, but if you practice constantly how to move arms, feet, and hold your breath you can make it excellent. The same goes for learning, everything is a process in which some of us sink because we don't know how to get good results, but if you try day after day, you learn a technique to cope with learning and not drown because you don't know how to handle it. It is significant, it is real everything is a matter of knowing how to do things and thus float on the surface without drowning.
