The sentiment expressed in the picture you see here is rooted in insecurity that is born from improper and unhealthy thinking about the origin of value for human beings.
Nobody who lives with thinking such as this can ever be happy.
The truth is that no matter what you ever do, you will always be an average (regular) human being. You will never be more, you will never be less. There is nothing you can do or not do to change this reality.
The same way that sparrows can only achieve things within the limits of all sparrows (no matter how hard they try, they will never suddenly begin achieving things beyond what is within the limits for all sparrows, such as suddenly achieving things only possible for eagles), you and I as human beings can never exceed the limits of what normal - or average - human beings are capable of.
What this means is that everything human beings have achieved is restricted to only what normal people in general are capable of.
Not even Michael Jordans, Neil Armstrongs, or Albert Einsteins are any more exceptional than anybody else - since even they are only working with capabilities that are inherent to all of us as human beings.
But here’s the most important part: When it comes to assessing the value of human beings as human beings, none of what we’ve done matters in the end anyway, since it’s not what human beings accomplish or don’t accomplish that creates our individual value as human beings. What creates our individual value as human beings is what we are, not what we do.
True security and contentment comes from understanding this and embracing it, not rebelling against it.
