A good guide for motivation and success in life would be the book Think and Grow Rich by Napoleon Hill. He is truly the master of getting to perfect yourself, both emotionally, psychologically, as well as influencing things around you. Currently reading it, as it is one of those books you cannot actually 'finish'.
Nevertheless, good guide my man, had to come back and comment on this one post because of how it helps me with my real life. Stick to helpful tips like these and you'll go far in life :)
“Before success comes in any man’s life, he is sure to meet with much temporary defeat, and, perhaps, some failure. When defeat overtakes a man, the easiest and most logical thing to do is to quit. That is exactly what the majority of men do. More than five hundred of the most successful men this country has ever known told the author their greatest success came just one step beyond the point at which defeat had overtaken them.”
