Both men agree that relentlessly focusing on one specific passion or problem leads to achievement. And that means pushing aside other ideas and interests until a goal is reached, according to TIME.
Buffett biographer Alice Schroeder writes, "He ruled out paying attention to almost anything but business—art, literature, science, travel, architecture—so that he could focus on his passion."
But focus alone is not enough. Putting in the time to commit to something is also crucial to achieving success.
In the past Buffett has said that, "successful investing takes time, discipline and patience. No matter how great the talent or effort, some things just take time: you can't produce a baby in one month by getting nine women pregnant."
