I have always had a strong interest in knowing great people in my field i.e., programming. Knowing about them, following them, and reading them not only gives you immense knowledge but the motivation you need to excel in what you are doing.
It's motivation, not the knowledge that will propel your career. Knowledge is useless without motivation because knowing is not enough, you need to apply that knowledge, and without motivation, you just can't do that. There are times when the programmers also felt tired and bored. These are the times when you spent hours constantly looking at the computer screen, clicking here and there, surfing the net without doing anything.
