I think it's more that you get good at what you practice. Someone who goes out every night of the week is practicing social interaction, and they will probably get pretty good at it. Someone who spends time with their family will have a strong family relationship. Someone who watches TV every night of the week will know an awful lot about the TV shows currently on the air. Someone who plays Farmville or Scramble with Friends or StarCraft with all their spare time will get pretty good at that. Someone who spends a lot of time on Hacker News will have really high karma.

And then ask yourself: is the stuff you're good at the stuff you want to be good at? Because if you want to be good at StarCraft or TV trivia and that's what you do with your spare time, great. But if you want to be good at programming but it's not your day job and you spend all your free time watching TV, you have some problems. Similarly, if you want to have a strong family relationship but spend all your time programming or holed up in your man-cave, you also have some problems.
