So you propose to be unhappy and dwell on the things that one can't control? I have heard no realistic solutions, just soothsaying and hand wringing. Give me something real that I can do, that I'm not already doing, and I'll do it. I choose to not be miserable and panicked about it though-- it's a pointless exercise.
Go to your city council meetings. Argue to remove minimum parking requirements. Argue for mixed use zoning. Support public transit projects, affordable housing projects.
