Some say we're all likely to have multiple careers in life. Others say we should have multiple careers at once. That's the argument advanced in a column by writer Kabir Sehgal in the Harvard Business Review: That your best bet is to have more than one career track at the same time.

His column itself drifts pretty hard into humble-bragging, but I have to agree with his central premise: If you have the means to do it, you're better off pursuing more than one occupational interest at once. It's nice if you can pursue at least one of them as a side gig or a hobby, but there are many paths to the same goal.

The real value here (aside from having a fallback, in case things go wrong in your primary track) is that you learn things from working in one area that can be useful in the other, and vice versa. The cross-pollination of ideas turns you into a more valuable employee/contractor/boss/hired gun than you would be with a single-track mind. So while pursuing two careers at once might soak up some of your free time, it might also make you a natural leader and innovator -- which in turn can mean you get to charge a lot more money for your ideas and skills.
