Please permit me to add this simple story.
You've got 6 hours per day to study and your goal is to score A1 in chemistry (because it's the only thing that matters). But because you like physics, geography, and maths you then shared your 6 hours into 4 places to study other subjects.
Your friend Peter uses the same 6 hours to chemistry. Results came out; you scored C6 and he scored A1. You complained you studied hard for 6 hours everyday. But Peter was more focus than you are. Results will never be the same.
When it comes to achievement, amount of input determines the kind of outcome you get. Multitasking will only reduce the time you've got to input in a thing.
exactly, you gave a perfect description of the whole context of my post.
Exactly.. thanks for dishing this out.
