I don't disagree. It's an option to consider. There are also customer-facing roles that are more technical (systems engineers, solution architects, etc.) and various gradations between those and sales generalists.

With that said, a couple caveats.

1. There are definite personality and skill sets that fit well with sales--or at least the sort of outside sales job one would aspire to. Some of this can probably be learned but it comes more naturally to some people than others.

2. Sales tends to be very performance-oriented. On the one hand, it means it may be easier to land a sales role. On the other hand, you have to make your numbers or you won't be around long.
