There is more worth in a dumb but hard-working person, than in a smart and lazy one. Too many people strive to be the smartest around but few try to work hard and consistently.
I can't be a judge of how smart you are, but being hard-working is a choice you can make. Blocking HN is a good start.
> I divide my officers into four groups. There are clever, diligent, stupid, and lazy officers. Usually two characteristics are combined. Some are clever and diligent -- their place is the General Staff. The next lot are stupid and lazy -- they make up 90 percent of every army and are suited to routine duties. Anyone who is both clever and lazy is qualified for the highest leadership duties, because he possesses the intellectual clarity and the composure necessary for difficult decisions. One must beware of anyone who is stupid and diligent -- he must not be entrusted with any responsibility because he will always cause only mischief.
The same quote is often attributed to Napoleon and probably suits the army well. There is also a world of a difference between enthusiastic and hard-working. I'd say being energetic falls into the same bucket as being smart (lets call it 10x things), whereas working steadily or being careful and methodological into the other, of things useful for building larger structures.
