Every felt like you were the only one among your peers who is stupider than the rest, and has to work harder than everyone else to achieve what they can?
In Stanford, we have a term called the 'Stanford Duck Syndrome'. Here's the illustration:
You see everyone else (the ducks) bobbing casually on the water, chilling out, having a good time. But you don't realize that under the water, the ducks are paddling like mad with their feet trying to move forward.
Next time you feel a lack of confidence in your abilities, or that you have to be more diligent than the rest, remember that all is not what it seems on the surface. Everyone has their own problems, just that they don't show it. So, just do the best you can, and stop worrying about how other people may be coping better, because they are having a tough time as well!
