go wfp...lol
youll get used to it buddy, first time i went up my face was stuck to the glass, how i cleaned it i dont know, but few goes and as said before youll be running up there! be careful though. one tip, if you think you cant reach that corner in the window, dont ever over stretch, think about what your doing, those few seconds it would have taken you to just come down and move your ladder could of saved you a tumble.
this is how you want your ladder pretty much
i used to put my ladders underneath the sill which can be a little awkward sometimes, but if you put it on their sill you may damage/mark it. go steady up and just hold the underneath of the sill with a polo grip claw, lol. and just remember be careful and dont over stretch, its simple. ladders arent dangerous...they are only if you make them i.e. over stretching, not putting them on level ground, the right angle.
if your that worried why not look at something like this, this ones called ladder stopper. there s another one that has been talked about on here but i cant remember where
good luck and just take your time, speed will come...i hardly go up ladders now probably about once a month and im like a wet lettice when i go up and ive been doing this 5 years!
by the way i wouldnt reccomend this lol
