Good sense
Good sense is the most equitably distributed of all things because no matter how much or little a person has, everyone feels so abundantly provided with good sense that he feels no desire for more than he already possesses.
I regularly feel like I don’t know anything. I have been working as a software developer for around 8.5 years and I feel like a green newbie who just came out of University. The internet serves as the greatest asset to my professional life but also the greatest ego bruiser I have ever known.
Experience can be a handicap… At forty-two (or three!), it's easy to think you know things. You’re at incredible risk of thinking you know things when you’ve achieved some measure of success, no matter how modest. You become “unconsciously incompetent.” You don’t know, but you don’t know you don’t know.
