Staying current with knowledge

[gizbug]

With so much knowledge and information to know and retain, what are some ways you users stay current and up to date with flight knowledge? There have been a lot of rainy days here in Michigan, and I have been just browsing through books getting ready for a CFI check ride, but I am curious how others on here retain, and stay current with the abundant amount of information out there. I know this forum helps me out a lot.

In my last few instructing jobs (Chief Flying Instructor or multi IFR etc) every 6 months to a year I'd read the rules & regs from cover to cover.

I'd start with the Act, then the Regulations then the Orders then the AIP then the approach plate documentation.

In the USA I suppose that would just be the FAR/AIMs?
