I'm getting back into learning CSS. It's still hard (my brain is weak from non-use) but I have a lot less going on now than I did the first time round.
Because of the holidays and decreased volume at work I have a lot more time on my hands. Winter is typically when I work on updating my process manual and situating things for next year. So, in between those projects I'll have plenty of time to devote to learning new and tricky things.
Maybe this time it will stick?
