I sympathize with you! I'm dealing with reluctance because change
introduces risk and if it ain't broke, don't fix it. My strategy is to
keep the concepts in my toolbox and pull them out when a business need
arises. Sometimes stuff happens and you can suggest a best practice
that wiil prevent an issue from happening again. I know it's better to
be proactive, but sometimes you need to be reactive until the
advantages of best practices are obvious to everyone.
