I work in shopping center development so I, for one, have something to be worried about. However, we have a good portfolio of operating centers to carry us in a down market. If need be I can cut back my hours during the lull periods, work on just entitlement projects (we have several big projects in Entitlement that will take 2+ years), and travel a bit. I have prepped for this by getting rid of all my debt and moving to investments that generate secure steady incomes.
