"Golden child" siblings

I have one child, who, for the most part, simply has an easier life than his brother. By that, I mean that he picks up skills (athletic and academic) faster and is by nature more organized and more adept with social situations. This is not to say his brother doesn't have amazing qualities, too; he really does and I am so proud of him. It's just that he tends to have to work harder at almost everything, and I can see that this can be frustrating for him. I make an effort to focus on the particular talents of each one, and I encourage them to them cheer for each other's accomplishments. But at some point, should I sit down with my one son and simply give it to him straight that yes, some people just have to work harder in life? I'd also tell him that this isn't necessarily a negative, because he may feel a greater sense of pride when he does meet his goals. He also will naturally learn to perservere when the going gets tough, which he has done so far (that's a big reason why I'm so proud of him!). At the same time, I don't want to assume that my other boy is always okay and doesn't need my help too. If anyone else is in this situation, please let me know what has helped your kids and prevented some jealousy!
