One of the most under appreciated and unrecognized traits of successful people is Enthusiasm. It's incredible actually, just how much enthusiasm can act as a counterweight to a deficiency in another area.

Companies often get funded based on the enthusiasm of the founder. Employees are given promotions over workers that might technically be more skilled because of enthusiasm. Acquisitions are completed because of enthusiasm. 

Presidents are elected not on their experience or their intellect, but by the amount of enthusiasm they're able generate. 

Of course, the reverse of this is also true.

People often get divorced not because of the intense arguments, but because of the absence of enthusiasm for each other's successes. You can be technically proficient, intelligent, etc., but if you don't like what you do, if you're not pleasant to be around, that can overwrite a great number of your qualities.

I think it's important to be aware of this reality on a regular basis. People shouldn't be disingenuous of course, but if you're able to regularly look at the world and your work through a lens of excitement, I think that's a special trait, and one that's likely to ultimately make you and others better off.

And of course, the real opportunity this presents is that Enthusiasm is free, requires no experience, and is a massive multiplier. The challenge is that it requires effort, insight and importantly requires you to be vulnerable.

Once again, therein lies the opportunity.
