Not like riding a bike.

[Ziggurat]

I must say this "skill" is not 'just like riding a bike.'

I took just over a year off of this activity, and now I have extreme difficulties doing it again. I can barely get it in there, when I do get it in it doesn't like to stay. As far as I know I'm doing the same stuff I used to do. If I try to move once its in, it just pops back out.

So, my advice to all of you my friends is: once you learn this skills, if you like it, don't ever take more than a month off away from it. Its not something you ever master.
