changethis.com is a great source of free self-help and motivational booklets in pdf format. These nice booklets are called ‘manifestos’. These pdfs are nicely formatted and optimized for pleasant reading on your computer screen.
Many of these manifestos have been written by best seller authors. There are great manifestos on topics which include marketing, motivation, personal grooming, time management, creativity, writing etc.
changethis.com was founded by Seth Godin. I discovered this website many years ago when some one pointed me to a free pdf book by Seth Godin titled “The Bootstrapper’s Bible“.
