How embarrassment and self-awareness helps you build thoroughness and attention to details.
The human brain is a formidable machine.
Get yourself doing the same task over-and-over-and-over, and your brain will start shaping itself around that task.
If you’re an interface designer, chances are you’ll build a special eye for type sizes, alignment, color tones. If you’re focused in UX, your brain will likely be stronger in skills like systematic thinking, flow definition, hierarchy and consistency.
The same applies for spotting errors.
