My lack of periodization is probably one of the reasons why I don't climb that hard (yet ;)). Although I must admit my approach towards climbing has changed in the last two years.
One of the issues with my approach is that I don't take enough rest (I hate restdays). Unfortunately this means that every now and again I'm run down. Which is exactly what happened the last two weeks.
Fortunately Andy knows when I'm run down and he is the only one who can make me take a restday. So, he 'made' me take two restdays back to back, which did the trick. My restdays payed of straight away, as I did Worldline first go when I pulled on it again on Sunday and it felt piss this time.
I might try a 'bit of periodization' after South-Africa, see where it gets me ;)).
