Humbleness, a quality we appreciate in others, but we don’t usually personally aspire. In the tech community humbleness is most often seen as weakness. Even though it’s so nice when being surrounded by colleagues who are humble, yet very few aspire for that quality themselves. Most often is the complete opposite: competition. Competing on salaries, power or titles.
But on a personal level, there’s so much growth in remaining humble. Even when one gains a certain mastery over his profession, still having the wisdom and courage to remain consciously humble, is the greatest reward.
