No one can focus at 100%. The key is to starve. Compulsions and habits are the things that break in focus. You've got to be good at catching the feeling of being like, all this is what I want to do. But nope, just about it.
Finding focus in a world full of distraction can be an extremely hard thing to obtain. Sometimes we need to think outside the box by inverting the equation and adjusting our lens to which we view things. The first step toward finding focus is to ask yourself "what is the opposite of focus?" -Distraction. We can then identify our main distractions and eliminate them one by one, taking back control of what our mind focuses on.
