Books—they weren't ladders out of the abyss, but they were companions. - John Green
The right thoughts of the clever man are a ladder which takes you higher places. By climbing these ladders, one day you yourself become such a ladder itself! - Mehmet Murat ildan
You must write every single day of your life... You must lurk in libraries and climb the stacks like ladders to sniff books like perfumes and wear books like hats upon your crazy heads... may you be in love every day for the next 20,000 days. And out of that love, remake a world. - Ray Bradbury
