Agree with Step….I recently had to do my one hour of dual for my SEP revalidation, so asked the instructor if we could practice various approaches to short landings. Turned out to be the best hour of instruction ever spent, we duly practiced the short field approaches and then he started throwing in all sorts of emergencies, power cuts in awkward places etc. I came down feeling slightly wrung out, but it made me realise the importance of the occasional 'lesson', which frankly is not always a high priority for most share/sole owners. It made me think that I should be doing this more often, perhaps once every three months or so just to stretch and improve my skills, definitely better value than a new 'shiny toy'
