Become a product manager (at least part-time). I was a developer for 7 years and never progressed towards PM, so I've just left my company, created my bootstrapped start-up because no-one would ever believe in me, got experience at copywriting, marketing, negociation, product roadmap planing, went to conferences, talked at some, (all of those in addition to developing the product obviously), sold enough copies within the first year to make a nice living... I think I've proven my point that I'm not bad at it, as opposed to the stigma we face when we're programmers, so next year I hope to be hired in a proper company to do the same job.
