Productive people specialize. Now that doesn't mean if you're an engineer, you can never go to the opera, you can have a wide range of interest. But if you want to be successful in your career, most of the time you need to really, really specialize. Michael Jordan may have tried to play professional baseball and golf, but he was good at basketball and that's where he spent almost every waking second. The first 35 years of his life is playing basketball. That's why he was good.
Ronaldo was a great soccer football player. But he didn't go out for his country's weightlifting team for the Olympics. He didn't try to make the volleyball team for the Olympics. He focused on soccer, excuse me football for the rest of you outside the United States. highly productive people are productive because they focus their energies and It's the old analogy of the magnifying glass. You can make fire you can ignite something when you concentrate to a narrow point.
By focusing all your energies, your productive energies, you stand out from the competition, you're able to gain traction, you're able to accomplish so much more. You might not know yet what your area of focus is, but you can at least be thinking about it every day. You can be experimenting and testing every day, nothing else, crossing off things that are not going to be your main focus in life.
